4 types of stone crushers' maintenance and efficient improvement | fote machinery

There are different types of stone crushers in mining industry such as jaw crusher, cone crusher, impact crusher, and sand making machine. This article will tell you how to maintain the 4 types of rock crushers and how to efficicently improve their performance.

Many stone crusher operators have a common coception that is "don't-fix-it-if-it-isn't-broke". They may want to save cost at the begining while the consequence is that they have to spend more money on repair and face interuption on production. That's why I always say that preventive and predictive is very important for all types of stone crusher.

Preventive means that by making regular checklist and inspections to keep crushers in good condition. Maintenance checklist is usually set up on a daily (8 hours), weekly (40 hours), monthly (200 hours), yearly (2,000 hours). Only doing that, can you prolong the machine's life span and maximize its value in crushing process.

Predictive refers to mornitoring the condition of crusher when it is running. By some maintenance tools such as lubricating oil temperature sensors, lubricating oil filter condition indicator, you can timely draw the machine data so that making a comparison between the real situation and normal state. Predictive can help you find problem early then timely removing thers issues before demage occuring.

Ractive means that even if your crushers have got problems, as long as you adopt correct solutions to respond, you still can get your machine back to normal. Next, I'll introduce important skills to maintain your equipment.

The cone crusher in the secondary or tertiary crushing proccess often fractures medium-hard or hard rocks like pebble, quartz, granite, etc. It is easy to get premature crusher failure, if operators cannot make a correct and timely inspection and maintenance.

Mantle in moveable cone and concave is fixed cone. Due to directly contacting with rock materials, the two wear parts need frequent maintenance and protection. So operators have to know the preparations and maintaining skills.

The working principle of impact crusher is that the spinning rotor under the driving of the motor can genetate strong impact force which make blow bars crush stone material into small pieces. Then the crushed material would be thrown by hammers towards, which makes another crushing process "stone to stone".

The sand making machine is also known as the vertical shaft impact crusher. Its working mode is that the material falls vertically from the upper part of the machine into the high-speed rotating impeller. The impeller is one of the important parts of the sand making machine, and it is also the most vulnerable part.

After the materials collide with each other, they will be pulverized and smashed between the impeller for multiple times and discharged from the lower part. The materials crushed by the device have an excellent particle size and are suitable for aggregate shaping, artificial sand making and highway construction.

In the face of such a dazzling market, how to choose the production equipment suitable for users' actual needs among the numerous equipment brands of many machinery manufacturers is a big problem for many large and small enterprises.

crushers - all crusher types for your reduction needs - metso outotec

All rock crushers can be classified as falling into two main groups. Compressive crushers that press the material until it breaks, and impact crushers using the principle of quick impacts to crush the material. Jaw crushers, gyratory crushers, and cone operate according to the compression principle. Impact crushers, in turn, utilize the impact principle.

As the name suggest, jaw crushers reduce rock and other materials between a fixed and a moving jaw. The moving jaw is mounted on a pitman that has a reciprocating motion, and the fixed jaw stays put. When the material runs between the two jaws, the jaws compress larger boulders into smaller pieces.

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action.

The chewing movement, which causes compression at both material intake and discharge, gives the single toggle jaw better capacity, compared to a double toggle jaw of similar size. Metsos jaw crushers are all single toggle.

Gyratory crushers have an oscillating shaft. The material is reduced in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly.

The fragmentation of the material results from the continuous compression that takes place between the liners around the chamber. An additional crushing effect occurs between the compressed particles, resulting in less wear of the liners.

Cone crushers resemble gyratory crushers from technological standpoint, but unlike gyratory crushers, cone crushers are popular in secondary, tertiary, and quaternary crushing stages. Sometimes, however, the grain size of the processed material is small enough by nature and the traditional primary crushing stage is not needed. In these cases, also cone crushers can carry out the first stage of the crushing process.

Cone crushers have an oscillating shaft, and the material is crushed in a crushing cavity, between an external fixed element (bowl liner) and an internal moving element (mantle) mounted on the oscillating shaft assembly.

An eccentric shaft rotated by a gear and pinion produces the oscillating movement of the main shaft. The eccentricity causes the cone head to oscillate between open side setting and closed side setting discharge opening.

The fragmentation of the material results from the continuous compression that takes place between the liners around the chamber. An additional crushing effect occurs between the compressed particles, resulting in less wear of the liners. This is called interparticular crushing also.

Depending on cone crusher, setting can be adjusted in two ways. The first way is for setting adjustment to be done by rotating the bowl against the threads so that the vertical position of the outer wear part (concave) is changed. One advantage of this adjustment type is that liners wear more evenly.

To optimize operating costs and improve the product shape it is recommended that cone crushers are always be choke fed, meaning that the cavity should be as full of rock material as possible. This can be easily achieved by using a stockpile or a silo to regulate the inevitable fluctuation of feed material flow. Level monitoring devices detect the maximum and minimum levels of the material, starting and stopping the feed of material to the crusher, as needed.

Impact crushers are traditionally classified to two main types: horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other.

Horizontal shaft impact (HSI) crushers are used in primary, secondary or tertiary crushing stage. HSI crushers reduce the feed material by highly intensive impacts originating in the quick rotational movement of hammers or bars fixed to the rotor. The particles produced are then further fragmentated inside the crusher as they collide against crusher chamber and each other, producing a finer, better-shaped product.

VSI crusher can be considered a stone pump that operates like a centrifugal pump. The material is fed through the center of the rotor, where it is accelerated to high speed before being discharged through openings in the rotor periphery. The material is crushed as it hits of the outer body at high speed and due to rocks colliding against each other.

Selecting optimal crushing equipment can be difficult. Luckily there are tools and software available that simplify weighting different options and help in making decisions. The backbone of all these analyzes are careful calculations that take into account the capabilities and constraints of different crushers and operational requirements.

Every crushing site and operation is different, and theoptimal results are normally obtained by combining theoretical conclusions with practical experience of different materials, operational conditions, maintenance needs, and economic aspects of various alternatives.

Below are some key issues listed according to crushing stages in brief. While defining the best technical solution for your requirements, its good to remember that many crushers are available not only as stationary but also asmobileorportableversions in case you prefer to move or transport your crusher at the production site or between sites regularly.

If you are interested in more detailed analyzes tailored just for your crushing operations, please contact Metso experts. We have practical experience of thousands of different crushing applications around the world, and we are happy to help in finding the equipment that best fits your needs.

The main purpose of a primary crusher is to reduce the material to a size that allows its transportation on a conveyor belt. In most crushing installations a jaw crusher takes care of primary crushing. Plants with very high capacities that are common in mining and less popular in aggregates production, normally use a primary gyratory crusher. When the processed material is easy to crush and not very abrasive, an impact crusher may be the best choice for primary crushing.

One of the most important characteristics of a primary crusher is its capacity for accepting feed material without bridging. A large primary crusher is, naturally, more expensive than a smaller one. Therefore, the investment cost calculations for primary crushers are compared together against the total costs of primary stages, including quarry face clearing, blasting, and drilling costs. In many cases, dump trucks transport the rock to a stationary primary crusher. This may be an expensive solution. Amortization, fuel, tires, and maintenance costs can be included when the vehicles are in high demand. In modern aggregates operations, the use of mobile primary crushers that can move alongside the rock face is, in many cases, the most economical solution.

In terms of the size of the feed opening, the client gets a better return on investment when the primary crusher is a jaw crusher. That means less drilling and blasting because the crusher accepts larger boulders. The disadvantage of this type of crusher, when high capacity is required, is the relatively small discharge width, limiting the capacity as compared with the discharge circuit of a gyratory crusher. Jaw crushers are mainly used in plants producing up to approximately 1600 t/h.

The primary gyratory crusher offers high capacity thanks to its generously dimensioned circular discharge opening (which provides a much larger area than that of the jaw crusher) and the continuous operation principle (while the reciprocating motion of the jaw crusher produces a batch crushing action). The gyratory crusher has no rival in large plants with capacities starting from 1200 t/h and above. To have a feed opening corresponding to that of a jaw crusher, the primary gyratory crusher must be much taller and heavier. Also, primary gyratories require quite a massive foundation.

The primary impact crusher offers high capacity and is designed to accept large feed sizes. The primary impact crushers are used to process from 200 t/h up to 1900 t/h and feed sizes of up to 1830 mm (71") in the largest model. Primary impact crushers are generally used in nonabrasive applications and where the production of fines is not a problem. Of all primary crushers, the impactor is the crusher that gives the best cubical product.

If the intermediate crushing is done with the purpose of producing railway ballast, the quality of the product is important. In other cases, there normally are no quality requirements, except that the product be suitable for fine crushing.

Due to their design, cone crushers are generally a more expensive investment than impactors are. However, when correctly used, a cone crusher offers lower operating costs than a conventional impact crusher. Therefore, clients crushing hard or abrasive materials are advised to install cone crushers for the final crushing and cubicising stage.

Cone crushers can in most cases also give a good cubic shape to fine grades. They can be adapted to different applications. This is an important factor, as client-specific needs often change during a crushers lifetime.

The conventional type has horizontal shaft configuration, known as HSI. The other type consists of a centrifugal crusher with vertical shaft, generally known as VSI. Impactor operation is based on the principle of rapid transfer of impact energy to the rock material. Impactors produce cubic products, and they can offer high reduction ratios as long as the feed material is not too fine. This means that in certain cases it is possible to use a single impact crusher to carry out a task normally done in several crushing stages using compressing crushers (i.e., jaw, gyratory, and/or cone crushers). Impactors are mostly used for nonabrasive materials.

Conventional horizontal-shaft impact crushers are available in various sizes and models, from high-capacity primary crushers for large limestone quarries to specially designed machines for the crushing of materials such as slag.

There are two main categories of VSI crushers machines with impact wear parts around the body and machines that use a layer of accumulated material. The first type is in many respects similar to the conventional impactor with horizontal shaft and rotor. The second type became quite popular in the past decade and is known as the Barmac crusher. The difference between a conventional impactor and a VSI of the Barmac type is that the latter offers lower operating costs, but its reduction ratio is lower also. In a Barmac VSI, the material undergoes an intense rock-on-rock crushing process. In the other crushers, most of the reduction is done by the impact of stone against metal.

Customers operating old, rebuilt, or expanded plants often have problems with the shape of the product. In these cases, the addition of a Barmac VSI in the final crushing stage offers a solution to product shape problems.

The same applies to many mobile crushing units. As the number of crushing stages is normally small with this type of plant, it is almost impossible to obtain a good product shape unless the rock is relatively soft and thus more suited for the production of cubic product. A centrifugal crusher in the final stage can help to solve the problem.

regular crusher maintenance integral to reliability, performance and output - international mining

regular crusher maintenance integral to reliability, performance and output - international mining

Crushers operate at high power, force and capacity in order to produce the required materials. Weir Minerals told IM: This puts a great deal of strain on the crusher and its wear parts, which operators must be aware of when carrying out maintenance. Failure to do so may have a high impact, both in terms of financial cost and potential loss of production.

Performing regular maintenance on crushers is integral to the reliability, performance and output they achieve. Prevention is better than cure; by carrying out regular inspections operators will ensure their crusher runs for a longer period of time with minimal unscheduled downtime. The most important aspect is to have a maintenance plan in place and execute it. Following a maintenance plan and carrying out daily inspections can yield increased service life. This maintenance plan should adhere to the recommendations of the manufacturer, states Eric Jones, Global Service Director of Comminution Aftermarket for Weir Minerals.

The maintenance plan may differ slightly, depending upon the machine, but most follow an initial 40 hour schedule post commissioning, followed by regular 250 hour inspection/maintenance intervals throughout the annual cycle. Within these intervals, there are prescribed tasks an operator will need to carry out. These include:

If operators do not follow a maintenance plan and carry out daily inspections, it can have detrimental effects on the crusher. When it comes to insufficient maintenance inspections, the most common problems Weir Minerals has witnessed are premature bearing failures. For example, operators failing to notice that a breather has been knocked off, which fills the oil chamber with dust or debris; overlooking the grease line that has ruptured causing the bearing to no longer receive the required lubrication; or not checking the oil levels and having a bearing fail due to the lack of oil. These are all common problems which can be avoided if a full maintenance plan is put in place and adhered to.

Whilst wear replacement is a necessary feature of any crushing operation, there are steps operators can take to extend the service life of crusher wear parts. Jones advises: Always ensure the wear parts are fastened into the machine properly. With jaw crushers, if you allow the jaw dies to move during operation they can cause damage to the frame of the jaw crusher. Similarly, loose liners in cone crushers may damage the head or bowl.

It is also advisable that operators frequently look for holes, cracks, or flat spots, which could potentially damage the machine long term or be an indication of another issue. Further to that, operators should track tonnages. As cone crusher liners wear, the operator threads the bowl inwards, bringing the bowl liner closer to the head which reduces the feed opening. The reduced feed opening may decrease crusher throughput at a cost; once that cost is greater than the price of the liner change the operator should consider changing the liners. At a glance, the liners may still have what an operator would perceive as usable wear left, but at a lost tonnage that doesnt benefit the plant.

If an operator observes significant wear-part damage during regular inspections, they should consult the crusher manufacturer to find out if immediate stoppage is warranted. Determining whether to stop production to change a wear part entirely depends upon the severity of the damage. For example, a damaged rotor tip in a VSI crusher may make it through the shift and not cause unwanted downtime. However, a broken jaw die with parent steel exposed may cause significant damage, and it is vital the operator stops the jaw crusher and change the die in order to protect the crusher frame, says Jones.

Failing to take care of damaged wear parts can increase wear on the entire machine which can lead to expensive failures. A common misconception is that operators think they should wear jaw dies until they are completely flat or develop a hole or crack. By running these wear parts for a longer period of time, operators think they are extending the wear life, but in reality they may be causing unnecessary stress to the jaw frame. Another common mistake Weir Minerals has witnessed is that operators run cone crusher liners past their useful operational life. The lost tonnages can cost the operator money greatly exceeding the amount that a liner change would cost, states Jones.

Cone crushers have evolved from the earlier models introduced in the 1920s, with most manufacturers now designing cone crushers with advanced hydraulic systems to raise, lower and adjust the machines safely with minimal effort. To clear a cone crusher, users simply depress a button, click the mouse or toggle a switch. This removes the risk of people manually clearing a stalled cone crusher by hand or using straps, chains and rolling stock to adjust their crusher. At Weir Minerals, safety is our No 1 priority and our latest designs reflect this. Our Trio TP cone crusher range is designed with self-protecting features to help achieve high levels of mechanical reliability under severe operating conditions whilst ensuring the safety of both the operator and equipment, says Jones.

In addition, Weir Minerals latest Trio CTHT series jaw crusher includes a hydraulic toggle relief system. This innovative, built-in system protects the jaw crusher from overloads caused by uncrushable material. The hydraulic toggle is designed to be a reliable and safe relief system, without unnecessary complexity for the operator.

Eric Jones concludes: If an operator doesnt properly maintain their crusher, they may experience poor performance, and decreased service life of the machine. We suggest that operators seek expertise to create and execute a maintenance plan to increase the service life of their crusher. At Weir Minerals, our replacement parts and skilled service teams provide professional on-site training for operators personnel to ensure smooth, safe and efficient plant operations and maintenance.

The types of pressure crushers include jaw crusher, roller crusher, and gyratory crusher. The pressure type crusher uses two hard parts of the machine to press each other to crush rock material. For example, the jaw crushers use the fixed jaw plant and movable jaw plate.

The jaw crusher's main function is to reduce the size of the raw materials or large pieces of material to a sufficiently small size, so as to facilitate the next step of the crushed material. In the quarries and mine materials crushing plant, it is generally used as a primary crusher. The types of jaw crushers are single toggle and double toggle. The construction of the single toggle jaw crusher is compact and simple, and the transmission components such as eccentric shafts are less stressed. Due to the vertical displacement of the movable jaw is small, the material is less excessively broken during processing. Therefore, the wear of the movable jaw plate is less.

Compared with the simple pendulum type, the double toggle type jaw crusher has the advantages of lighter weight, fewer components, a more compact structure and uniform crushing, high productivity. 20-30% higher productivity than a simple swing jaw crusher of the same specification.

Tooth Roller crusher is a new product that is designed and developed according to the structure principle of Gunlock crusher in America. The machine has the advantages of small volume, high crushing ratio (5-8) , low noise, simple structure, convenient maintenance, high productivity, even particle size of crushed materials, low over crushing rate, convenient maintenance, etc. The mall roller crusher is widely used in the mining industry as a secondary crusher.

Gyratory crusher is a new type of crusher that can replace fine jaw crusher and cone crusher. It consists of a concave surface and a conical head, both of which are usually lined with manganese steel. The inner cone has a slight circular movement but doesn't rotate. The gyratory has the advantages of good finely crushing effect, large processing capacity, small vibration, simple maintenance, low cost, and less lining plate wear.

Impact crushers crush materials by impact rather than by pressure. The material is broken in the crushing chamber under the impact force. It can handle materials with side length less than 100-500 mm, with compressive strength up to 350 MPA. It has the advantages of a large crushing ratio and cubic particles after crushing. There are two types of impact crushers: Horizontal Shaft Impact(HSI) Crushers and Vertical Shaft Impact(VSI) Crushers.

In the sand making plant is one of the essential crushers. Cone crusher according to the crushing force is divided into Simmons spring type and hydraulic type. Hydraulic type is divided into single-cylinder and multi-cylinder cone crusher. According to the rotary speed, there are three types: low speed, medium speed and high speed.

The basic structure of cone crusher is similar to that of rotary crusher, but the range is larger. It rotates and presses against the stone on the side of the machine, where it falls into the lower chamber and is crushed again until it falls out of the bottom. Its advantages: reliable structure, high productivity, easy adjustment, and low operation cost.

Hammer crusher(Hammer mill) is broken by an impact between a high-speed hammer and material. This type of crusher is divided into two types: single rotor and double rotor. Single Rotor is divided into reversible and irreversible. Hammer crusher is mainly composed of the rotor, spindle, hammerhead, lining plate and impact plate. And it mainly crushing for coal, salt, chalk, gypsum, brick, limestone and so on. It also used for crushing fiber structure, flexibility, and toughness of strong broken wood, paper, etc.

The advantages of the hammer: larger crushing ratio, high production capacity, uniform products, less over-powder phenomenon, simple structure, light equipment quality, simple operation, and maintenance.

Sand crusher is also called VSI crusher. It is an indispensable equipment for artificial sand manufacturing plant. VSI crusher imported advanced German technology development and production, with the international advanced level. Its performance plays an irreplaceable role in the fine crushing equipment of various materials. There are two types of sand-making machine: stone hit stone and stone hit steel.

The upper and lower hitting guard plate is installed on the crushing cavity wall of the sand making machine. It makes the ore material to be crushed by the impact, friction or high-speed impact between the material and the lining layer formed by the material and the material accelerated by the flywheel when accelerating. The materials do not come into direct contact with the equipment. This method reduces the wear and tear of fittings and prolongs the service life. "Stone hit stone" sand crusher is suitable for material with high abrasion above medium hardness, such as basalt. And the finished product has good grain shape, but the powder content is a little more. So it is more suitable for aggregate shaping.

In the crushing cavity wall of the sand-making machine, the lower hitting guard plate is replaced by the perimeter guard plate. When the ore material is thrown out by the roller, it is directly impacted on the guard plate for many times and the crusher. Under the constant impact, and then the crushing cavity material impact, ore material broken more fully, and the finished material particle size smaller. The "stone hit steel" sand crusher is suitable for small abrasive materials below medium hardness, such as limestone, and the crushing efficiency is high. However, due to crushing depends on the impact, so wear parts are higher. The finished product is slightly worse, it is more suitable for sand-making.

iron ore crusher price, crushing machine for iron ore beneficiation

iron ore crusher price, crushing machine for iron ore beneficiation

Iron ore beneficiation begins with the milling of extracted ore in preparation for further operations to recoveriron values. Milling operations are designed to produce uniform size particles by crushing, grinding,and wet or dry classification. The capital investment and operation costs of milling equipment are high.

Crushing is a multistage process and may use dry iron ore feed. Typically, primary crushing andscreening take place at the mine site. Primary crushing is accomplished by using jaw crusher or gyratorycrushers. Primary crushing yields chunks of ore ranging in size from 6 to 10 inches. Oversize material is passed through additional secondary crushers and classifiers to achieve the desired particlesize.

In iron ore beneficiation operation, the raw iron ore materials will be first reduced to small particle size. It may require crushing the material tomaximize the production of minus 2mm. According to SBMs experience in crushing technology, we recommended the installation of acone crusher to reduce the minus 100mm pebblesand a VSI crusher machine to fine crush the cone crusherproduct.

The iron ore crushers with low price are also used in the industrial minerals, mining, recycling and general quarrying industries. A widerange of materials are processed through SBM iron crushers worldwide. SBM experts can customize crushing solution in iron ore beneficiation according to your requirements. Here are some popular iron ore crusher machine types. Please contact us for more information.

According to different final products applications, varioustypes of crusher equipment are required, such as jaw crusher for primary crushing, impact crusher and hammer crusher for secondary crushing, cone crusher for secondary and tertiary crushing. Iron ore crusher prices are different according to crusher types and production capacities.

The VSI crusher for iron ore beneficiation uses a unique rock-on-rockcrushing action whereby the feed materialgrinds and impacts against itself, minimizingwear costs and maintenance down-time. Thisis especially important in applications such asiron ore processing where the feed material istypically hard and abrasive and wear costs arepotentially very high.

Jaw Crusher Jaw crusher is available with stationary, mobile and portable applications. The jaw crushers combine a high reduction ratio and increased capacity with any feed materials: from extra hard rock to recycled materials. This is achieved through several unique features such as higher crushing speed, optimized kinematics, a longer stroke and easy adjustment.

the most practical jaw crusher repair and maintenance manual | fote machinery

the most practical jaw crusher repair and maintenance manual | fote machinery

Just like other stone crusher machines, jaw crusher also needs a regular repair and maintenance after a certain time of working, or it will get decreased service life because of severe wear of important parts.

So many customers have common misconception that jaw plates only need repair when appearing flat, holes, cracks. Actually if jaw plates wears badly, it is not only hard to repair but seriously affects the normal working of other parts, which then will take a great sum of money to change a jaw plate and maintain other parts.

The pitman drives the moveable jaw dies to push stone material towards stationary jaws, which would create strong pressing forces to both jaw dies. Therefore, if the pitman cannot get lubrication in time, it will be broken under the high pressure of material and interrupt the whole work.

Proper plan and preparation make the whole repair and maintenance ordered and effective, which helps operators save time, cost, and enhance their safety. You can make a checklist just like the following chart in which you can list need-checked jaw crusher parts with a different period then making a mark if you are done with them. This not only prevents missed inspections, but also makes the arrangement clear, and saves a lot of time.

The lubrication of the interface between the parts of the jaw crusher is very important. It can minimize the friction generated during the operation, make the whole jaw crusher run smoothly, and extend its service life.

Unlike gyratory crushers, the main lubrication used in jaw crushers is grease instead of oil. When using grease, there may be several different ways to inject it into the necessary lubrication points. It can be operated manually with a grease gun, an oiler or metering pump.

Eccentric shaft (pitman bearing): It is behind the moveable jaw plate, and together with flywheel with toggle plate to create a motion. So, the most important thing you must do is keeping a regular lubrication to eccentric shaft, or you will spend more than four hours in changing a new one when it is broken.

Main shaft To keep the main shaft in good lubricating situation, you need to guarantee enough geese between thrust plate.The grease added to the bearing box needs to occupy about 50% of its space and be replaced every 3-6 months. When changing the engine oil, please use clean gasoline or kerosene to clean the roller bearing raceways.

There are different jaw plates material in the market, and some of them suits for hard stone while other is not. Therefore, you have to choose the right jaw plate for your crusher. For example, generally the jaw plate of single toggle jaw crusher is not good at crushing strongly abrasive and hard stone material with large production.

The function of toggle plate is to adjust the outlet of the jaw crusher to the desired size. There are two specific methods: one is to replace the support pad between the toggle plate and the body frame, and the other is to adjust the two wedges between the toggle and the body frame.

Fote Company has more than 40-year manufacturing experience, mainly engineering different types of jaw crushers including PE jaw crusher, Dodge jaw crusher, Blake type jaw crusher(double toggle jaw crushers), single toggle jaw cruhser, etc., and all of them can be customized.

same same but different mining equipment reliability and maintenance - mro magazinemro magazine

same same but different mining equipment reliability and maintenance - mro magazinemro magazine

Equipment used in the mining industry is somewhat unique because it is dependent on the type of mining where the machinery is used. On the one hand, in oil sands mining, bucket wheels and draglines have been largely replaced by electric and hydraulic shovels, while in potash mining, two- and four-rotor continuous mining machines are used to cut the raw material, where it is then transferred to conveyors or underground electric shuttle cars that move the ore to surface processing plants. On the other hand, coal mines use track or wheel-mounted excavators with rotating platforms with either a scoop or bucket to load coal onto haul trucks for delivery to process plants, while hard-rock mines employ drills for extraction and conveyors to move the material to either crushers or mills of various design, such as ball, rod or hammer mills.

What is not unique are the systems on these machines that require maintenance. The mining industry using diesel engines, hydraulic systems, gear drives of different types and configurations, electric systems, motors and transmission systems with associated components should apply every advanced total equipment reliability maintenance or asset performance management program available to effectively compete in todays international marketplace.

Based on statistical information, maintenance costs in the mining industry vary from 30 50 per cent of operating expenditures, depending on the type and age of any particular mine. From initial machine design to its disposal, mining companies must consider issues related to reliability, maintainability and continuous improvement strategies, the necessary and ongoing training of maintenance specialists, easy access to replacement parts and components among a myriad of other important considerations.

If we start at the beginning, new equipment acquisition should consider cost (based on lifecycle costs of the machine to be replaced) and the design and ease of maintenance and operation. If the new machine is a prototype, the mine might consider this as an opportunity to work with the manufacturer to improve design, maintainability, reliability and other considerations. Questions to be considered are: Does the machine contain oil- sampling valves to easily permit sample taking from lubricated components? Are vibration analysis transducers mounted on rotating machine components for ease of monitoring vibration problems? How easy is it to carry out routine maintenance tasks such as oil filter, bearing or drive-belt replacement? In every case of new equipment acquisition, experienced, knowledgeable maintenance personnel should be involved.

Once the new unit is on site, a review of manufacturers maintenance procedures and recommendations should be undertaken, oil levels in all lubricated components should be checked, tire pressures or track adjustments confirmed, along with what is very often referred to as an on-site pre-delivery inspection to ensure compliance with the initial purchase order.

When new machines are installed in the process plant, they are often installed and commissioned by either the manufacturer or a contractor in either case the installation should be carried out with close cooperation and involvement of mine maintenance personnel. Very often the commissioning is done too quickly (and badly) when mine management insists that production continue as soon as possible. Having maintenance personnel involved in the installation and commissioning can provide an opportunity to prevent this lack of foresight and also provides access to learning about the new equipments operation for both mine maintenance and operating personnel. The old adage remains true: If you dont have time to do it right, when will it ever be done right? Poor machine operation can very often be traced back to inadequate installation or commissioning.

Once the equipment is operational, assuming it is considered production critical, its time to apply whatever reliability improvement strategies that can or should be considered. These should be based on an ongoing philosophy of continuous improvement that includes the application of condition monitoring technologies and this means that the mine should employ as many of these technologies as can be applied; for example, oil and vibration analysis, temperature and ultrasound monitoring should all be applied on every lubricated rotating machine that is considered critical to mine operation. These technologies should be applied on a regularly scheduled basis in order to gather machine condition data that can be effectively trended and recorded for easy access in the history files. (Remember that the trend is much more important than any particular set of data.)

As part of the continuous improvement philosophy, next apply reliability centred maintenance (RCM) on the new machine. Simply speaking, RCM is a process of improving machine reliability through a step-by-step approach to determine the potential failures of components within a particular machine by using a failure modes and effects analysis (FMEA). In too many cases, failures are discussed and analyzed only after they have occurred, which is of course the essence of reactive maintenance. By applying FMEA, we are determining the potential failure of a particular machine and its components before the failure and is the first step in being proactive in our reliability improvement failure avoidance strategy.

The analysis is carried out by maintenance, engineering and operations specialists usually led by an expert in the RCM process, often by a service representative provided by the equipment manufacturer or a consulting engineer well versed in the process.

Once each failure mode is identified and what happens when it occurs, the mine personnel can assess the consequences and decide what (if anything) should be done to anticipate, detect, prevent or correct it; or even design it out. Question 3 above is directly related to the use of condition monitoring technologies to gather the data needed to detect the potential failure. Consider the P-F curve that determines the relationship where a component failure can be predicted (using ultrasound or vibration detection, to the result of oil analyses all indicating an incipient failure, followed by an obvious increase in noise or temperature, resulting in a failure that could be catastrophic).

Contrary to popular opinion, the process of RCM using FMEA can be applied to both mobile machinery such as haul trucks, as well as process plant machinery like conveyors, crushers or ball mills. The results of implementing these reliability improvement strategies will most definitely reduce maintenance costs as well as reduce maintenance itself.

Even after the imposition of reliability centred maintenance, maintenance costs can be reduced by further reducing or eliminating maintenance activities. This can be achieved by extending the life of equipment and its components even further, as well as avoiding service failures. The key elements of further reducing maintenance costs are measuring the mean time between repairs (MTBR), or equipment life, the mean time between failure (MTBF), or equipment reliability, and the mean time to repair (MTTR) or equipment maintainability. By extending MTBR and MTBF and reducing the MTTR, costs can be reduced while production availability and yield can be improved. In addition, at least once each year, a team of maintenance personnel should review the preventive maintenance program using these regularly recorded data and consider even further maintenance activity reduction or elimination. Two examples of such improvements are the use of split bearings, dramatically reducing the time to replace conveyor bearings and the extension of oil drain intervals on haul trucks using oil analyses to monitor oxidation to determine remaining oil life.

An additional reliability improvement strategy that should be considered for improving plant equipment in the mining industry is the application of total productive maintenance (TPM) that minimizes the six big losses in process plants or production facilities. Its principle requirements are that everyone in the plant is trained to be responsible for minor maintenance, and overall equipment effectiveness (OEE) measures three key performance indicators availability, performance rate and rate of quality.

These three measures are divided into measuring and recording breakdowns and set-up adjustments, related to machine availability, machine idling/minor stoppages and speed losses both relating to rate of performance and process defects and start-up losses, relating directly to the rate of quality. An 85 per cent OEE is recognized internationally as best practice in any process plant. The calculation is:

There are many other best practice issues that should be considered or reviewed, such as unwillingness by management or maintenance to carry out root cause failure analysis on component failures because the failure is considered normal and therefore acceptable. (They are not!) Another problem is the application of short-term solutions to longterm problems without consideration for the consequences. A perfect example is the layoff of the plant oiler without an alternative plan that will result in lubrication-related failures within months or even weeks. Some mining management groups have failed to understand that a dedicated planning and scheduling function is critical to reducing maintenance costs. Finally, many mine managers consider maintenance as a cost rather than a cost-reducing asset. Ultimately, this short-sighted thinking can be disastrous.

crusher upgrades cut the cost of wear parts for boliden kylylahtis crushing operations at the luikonlahti concentration plant - metso outotec

crusher upgrades cut the cost of wear parts for boliden kylylahtis crushing operations at the luikonlahti concentration plant - metso outotec

Despite Bolidens Kylylahti copper mine having an estimated lifetime of only four years left, it paid off for the concentration plant to upgrade its jaw and cone crushers from the 1960s to Metsos latest models in a speedy installation process.

Together with Metso we calculated that the newC130 jaw crusher and GP330 cone crusher were a good investment for us. With our abrasive ore, they will help us cut our crusher spare parts costs. The savings will have a noticeable impact on our entire mines unit costs, estimates Janne Laukkanen, Bolidens Luikonlahti concentration plant Milling manager.

Due to the ores abrasive wear, the crusher settings must be adjusted often, and in the old crushers, this had to be done manually. With Metsos new models, the settings can be controlled quickly and safely thanks to a hydraulic adjustment system. Even single wear parts can be changed more quickly, explains Kaariaho.

From investment decision to installation at Boliden Kylylahtis concentration plant, the entire crusher upgrade project took just a little over three months, and the actual installation took four days. Metso Minerals Sales manager for southern Finland, Timo Sarvijrvi, made the profitability calculations of the upgrade for the mine.

At the end of the week, Bolidens crew dismantled the old Lokomo MK120C jaw crusher and the Ernest Thllman 5-foot cone crusher that was manufactured in East Germany. On Sunday evening, Metsos 6-strong installation team stepped into action on the work site.

After the crusher foundations were finished, the roughly 40-ton C130 jaw crusher and feed hopper were lifted using a mobile crane and shifted into place in the primary crushing plant, which is located on a slope. The 15-ton GP330 cone crusher used for fine crushing was lifted into the crushing plant in two pieces.

By Wednesday, the concentration plant was already able to test out the crushers, and by Thursday the power was connected and the first ore blocks were fed into the process. Actual production began right on schedule on Friday morning.

The ore is crushed into finer particles with secondary and tertiary (GP330) cone crusher, aiming to achieve 10mm particle size. Due to the abrasive nature of the ore, the GP330 has more options to optimize wear parts and get savings from it.

With the old crushers, the size of the ore particles heading for grinding was 12 mm, and we now want to reduce that to 10 mm. Thanks to the smaller mill particle size, we can reduce our comminution costs and also lower our electricity costs somewhat in crushing, says Laukkanen.

The Boliden Kylylahti concentration plant currently processes 750,000 tons of ore a year. The ore contains around 1.4% copper, 1.0 g/t of gold and 0.6% zinc. The plant produces copper and zinc concentrates. The concentrates are used by the companys own plants copper concentrate is used at the Harjavalta smelter and zinc concentrate at the Kokkola smelter.

The production volumes will remain the same, even though the new crushers would allow us to increase our capacity if need be. New mineral resources are explored all the time, and Boliden is, in fact, an active ore explorer in Finland, says Laukkanen.

failure to adequately maintain crushers comes at a high price

failure to adequately maintain crushers comes at a high price

Crushers operate at high power, force and capacity in order to produce the required materials. This puts a great deal of strain on the crusher and its wear parts, which operators must be aware of when carrying out maintenance. Failure to do so may have a high impact, both in terms of financial cost and potential loss of production.

Performing regular maintenance on crushers is integral to the reliability, performance and output they achieve. Prevention is better than cure; by carrying out regular inspections operators will ensure their crusher runs for a longer period of time with minimal unscheduled downtime.

The most important aspect is to have a maintenance plan in place and execute it. Following a maintenance plan and carrying out daily inspections can yield increased service life. This maintenance plan should adhere to the recommendations of the manufacturer, states Eric Jones, Global Service Director of Comminution Aftermarket for Weir Minerals.

The maintenance plan may differ slightly, depending upon the machine, but most follow an initial 40 hour schedule post commissioning, followed by regular 250 hour inspection/maintenance intervals throughout the annual cycle. Within these intervals, there are prescribed tasks an operator will need to carry out. These include:

When it comes to insufficient maintenance inspections, the most common problems Weir Minerals has witnessed are premature bearing failures. For example, operators failing to notice that a breather has been knocked off, which fills the oil chamber with dust or debris; overlooking the grease line that has ruptured causing the bearing to no longer receive the required lubrication; or not checking the oil levels and having a bearing fail due to the lack of oil.

Eric Jones advises: Always ensure the wear parts are fastened into the machine properly. With jaw crushers, if you allow the jaw dies to move during operation they can cause damage to the frame of the jaw crusher. Similarly, loose liners in cone crushers may damage the head or bowl.

Further to that, operators should track tonnages. As cone crusher liners wear, the operator threads the bowl inwards, bringing the bowl liner closer to the head which reduces the feed opening. The reduced feed opening may decrease crusher throughput at a cost; once that cost is greater than the price of the liner change the operator should consider changing the liners. At a glance, the liners may still have what an operator would perceive as usable wear left, but at a lost tonnage that doesnt benefit the plant.

Determining whether to stop production to change a wear part entirely depends upon the severity of the damage. For example, a damaged rotor tip in a VSI crusher may make it through the shift and not cause unwanted downtime. However, a broken jaw die with parent steel exposed may cause significant damage, and it is vital the operator stops the jaw crusher and change the die in order to protect the crusher frame, says Eric Jones.

A common misconception is that operators think they should wear jaw dies until they are completely flat or develop a hole or crack. By running these wear parts for a longer period of time, operators think they are extending the wear life, but in reality they may be causing unnecessary stress to the jaw frame.

Another common mistake Weir Minerals has witnessed is that operators run cone crusher liners past their useful operational life. The lost tonnages can cost the operator money greatly exceeding the amount that a liner change would cost, states Eric Jones.

Cone crushers have evolved from the earlier models introduced in the 1920s, with most manufacturers now designing cone crushers with advanced hydraulic systems to raise, lower and adjust the machines safely with minimal effort. To clear a cone crusher, users simply depress a button, click the mouse or toggle a switch. This removes the risk of people manually clearing a stalled cone crusher by hand or using straps, chains and rolling stock to adjust their crusher.

At Weir Minerals, safety is our No.1 priority and our latest designs reflect this. Our Trio TP cone crusher range is designed with self-protecting features to help achieve high levels of mechanical reliability under severe operating conditions whilst ensuring the safety of both the operator and equipment, says Eric Jones.

In addition, Weir Minerals latest Trio CTHT series jaw crusher includes a hydraulic toggle relief system. This innovative, built-in system protects the jaw crusher from overloads caused by uncrushable material.

Eric Jones concludes: If an operator doesnt properly maintain their crusher, they may experience poor performance, and decreased service life of the machine. We suggest that operators seek expertise to create and execute a maintenance plan to increase the service life of their crusher. At Weir Minerals, our replacement parts and skilled service teams provide professional on-site training for operators personnel to ensure smooth, safe and efficient plant operations and maintenance.

Weir Minerals offer 24/7 service and support, visiting operators on site to evaluate their maintenance issues and put a plan in place. With over 140 service centres, across 70 countries, Weir Minerals are wherever their customers need them to be.

Most mining operations can benefit from Metso Outotecs Chamber Optimization program. The concept of the program includes circular improvement cycles that can start with a single problem-solving event in a certain crushing stage and pass to the optimization of the entire crushing-circuit, one iteration at a time.

Chamber Optimization can improve the crushing performance by increasing the crushers wear life and maintaining the optimal chamber geometry during the crushers entire lifespan, significantly reducing production downtime. In parallel, it can improve the safety of site personnel by reducing the inherent maintenance risks that come with a liner change-out, states Rafael Yanata, Product Manager, Mining Crushing Solutions.

Another benefit is that the crushers wear parts can be tailored so that the maintenance schedule is synchronized with other crushers on site or crushing stages to avoid unexpected downtime with isolated liner change-outs.

Chamber optimization often results in improvements to production capacity. However, the total production capacity increase is not only coming from gains from a single crushing stage, but also from the interlinked downstream equipment. Crusher throughput capacity is not the only factor that needs to be considered. The key is to achieve the throughput levels with the proper gradation.

Crusher throughput capacity is not the only factor that needs to be considered. The key is to achieve the throughput levels with the proper gradation.

This can be achieved by designing an application specific crushing chamber and can be combined with crusher parameter changes such as modifying the closed side setting, stroke or countershaft speed. Downstream equipment capacity, coming from crushers, grinding mills or HPRG can be influenced by the feed material produced by the optimized upstream crusher. Finally, taking a holistic approach to the crushing circuit provides the best possible result, as each stage in the circuit has an influence over the other stages.

By running crusher and crushing process simulation softwares together, Metso Outotecs experts can identify production capacity improvement opportunities for both the targeted crusher and the complete circuit. In addition to immediate production capacity gains, taking a broader approach to production improvement can also help to reduce downtime. It can achieve this by extending the life of the wear parts or helping with additional recommendations that can speed up the relining event itself, leading to more uptime.

Metso Outotec has developed software such as Value Optimizer, that calculates the financial benefits for the optimization of a single crushing cavity or even the entire circuit. The software can calculate and project many key figures such as the direct savings, cost per tonne, increased production potential, sustainability contributions, safety and health improvement factors.

The recent launch of the MX Mantles technology for primary gyratory crushers makes doubling the wear life a new reality. For crushing chamber design purposes, Metso Outotec has developed a unique laboratory pilot test methodology. As a result, based on the ore properties, specific chamber parameters can be determined to define an optimal crushing cavity. Yanata noted.

Together with the crusher simulation tool, it supports designing a crushing chamber with the best combination of throughput capacity, product curve and specific energy consumption (kWh/ton), helping to achieve a globally optimal result.

The application of an optimized crushing chamber can reduce the energy consumption of a crusher by up to 30%, while still achieving the same reduction ratio and throughput capacity, said Onnela. An optimized crushing chamber profile can also influence the wear part lifetime drastically, further reducing the manufacturing and logistics related energy consumption. Onnela said.

First, from the manufacturing perspective, when we optimize parts and double the wear life, we are drastically reducing consumption which helps our products be more sustainable and more efficient. Consumption byproducts such as scrap material, melted steel, and all the energy needed for production can essentially be cut in half, explained Yanata.

We know that every crushing process is unique. Also, crusher feed material properties are changing over time depending on the ore deposit. The changes can be quite drastic, especially in the ramp up phase of a new operation. These were the driving factors that led to the conception of the Chamber Optimization program, Onnela added.
