optimized wears increase production at kmaruda iron ore mine - metso outotec

optimized wears increase production at kmaruda iron ore mine - metso outotec

During the wear parts and fine crushing development with Metso, KMARudas productivity figures went up, while milling time and energy costs decreased. The mine was able to process over 420,000 tons more iron ore per year, resulting in 193,000 extra tons of iron concentrates.

Thanks to the longer lasting wears and more efficient fine crushing, the grinding performance increased by 30%. The total grinding time needed went down by over 11,000 hours and energy consumption by 2.95 kW per grinded ton.

Actually, thanks to our improved productivity, we could change the technological scheme and move one grinding mill from the primary stage to the secondary one, says Main Grinding Specialist Vladimir Saveliev.

Across from its huge open-pit iron ore mines, KMARuda runs a rather small-scale, but efficient underground iron ore operation in Stary Oskol, southwestern Russia. The mines present ore extraction amounts to 4.8 million tons per year, of which 2.1 million tons of 66% iron concentrate is processed.Our cooperation began with cone and jaw crushers and now extends to pumps and wear parts development. Today we can well thank Metso for its support in constantly developing our mining processes. Any problems have been resolved quickly, and we have an excellent relationship, he adds.A few years ago, we faced difficulties with our processing equipment, mainly caused by the wet, extremely wearing, quartzite-containing ore. Then we learned about Metso and its crushers, pumps and wear expertise, says KMARudas Main Chief Engineer Alexander Munkh.

During the extensive cooperation on crusher wears, different manganese steel grades and alloys were tested on site. Today, the jaw crusher is operated with Metso MX jaws of a two-piece design. Metso MX technology is a new material solution for high-wear applications. Three cone crushers benefit from extra thick XT720 manganese liners, thus requiring less backing materials than normal.

With our old cones, we could achieve fines smaller than 13-14 mm. With the HP200 and HP500 cone crushers, the corresponding size is 6-7 mm. This has significantly added to our grinding capacity and decreased electricity and grinding wear costs, explains Alexander Borodin, Head of the crushing and grinding shop.

With our old pumps, we could achieve a lifetime of 2,5002,800 operational working hours. In 2010, we consulted Metso specialists and installed 6 vertical pumps for underwater use; today we can achieve a total lifetime of 9,00013,000 hours, says Andrew Pisarev, Main Engineer at the stowing shop.

In addition to the longer life, Metso pumps save 2530% in energy at the same capacity. Metso pumps are easy to service. We are cooperating further and studying the possibility to use some plastic parts at our underwater application, he adds.

jaw crusher vs cone crusher | advantages and disadvantages

jaw crusher vs cone crusher | advantages and disadvantages

Jaw crushers and cone crushers both are a classic laminated crusher. Also is the most mainstream crusher type. Jaw crusher is usually used as a primary crusher and second-class crusher. Cone crusher is usually used as secondary crusher or three-stage crusher machine. Jaw crusher and cone crusher are usually arranged on the stone crusher plant in two stages.

Jaw crusher breaks the rock to 10 ~ 30 cm size. Cone crushing machine further broke the stone to below 10 cm. Large cone crushers (gyratory crushers) also can as head crushers. Fine jaw crusher also can as a two-stage crusher, crushing stone to cm grade particle size range.

Cone rock crusher and Jaw stone crusher are a laminated crushing principle. Which is commonly known as the impact crushing principle The nature of crushing doesnt change too much, although the actuator of crushing use of different structure. The cone crusher adopts the extrusion process between the grinding wall and the crushing wall. Jaw crusher adopts the extrusion process between the moving jaw plate and the static jaw plate.

Cone crusher and jaw crusher are widely used, but the applicability of the two types of crusher is different. Jaw crusher has the most extensive adaptability and can meet the crushing requirements of almost any kind of materials. Cone crusher is also very wide applicability, but the Metso cone crusher price is high. Low corrosive materials can choose a low-cost impact crusher. Therefore, the applicability of metsos cone crusher has been reduced in economic consideration.

Cone crushing main advantages: High productivity, less power consumption, work more stable, small vibration crushing ratio, product granularity is more uniform, any side can give ore, and can be crowded to ore.

Jaw crusher main advantages: simple structure, low manufacturing cost, convenient maintenance, reliable work, small machine height, easy to configuration, high viscosity for the water ore is not easy to block.

Cone crushing equipment main disadvantages: Complex structure, equipment high costs, height. And need a higher workshop, machine heavy, inconvenient to transport, not suitable for crushing sticky ore, operation and maintenance more complex.

Fine jaw crusher is more used as a secondary crusher machine. It can crush the materials below 200mm to cm level. two jaw crushers can be equipped with the complete crushing production line. The single machine capacity of fine jaw breaking is low, and the breaking capacity of less than 100 tph can only be obtained by means of parallel connection of two machines.

Cone crusher as second-level crushing equipment, single machine crushing capacity of several hundred tons per hour. It occupies the absolute advantage in production capacity. Therefore, the fine jaw crusher can only be used in the secondary crushing station with small capacity. The cone crusher can be used in the secondary crushing station with a large capacity.

The matching of jaw crusher and cone crusher is based on the crushing segmentation. It is necessary to consider whether the particle size of jaw crusher can enter the cone crusher to form secondary crushing. For example, Compound Cone crusher configured in the back process of jaw crusher. The jaw crusher equipment broken too large discharge will plug the cone crusher feed mouth. Resulting crusher plant can not run smoothly.

For the matching of jaw crusher and cone crusher. It is necessary to compare the particle size range of the two materials. And adopt to the best matching range can obtain the most efficient production running state.

six steps to improve cone crusher performance - quarry

six steps to improve cone crusher performance - quarry

A cone crusher is punished during every minute of operation. It squeezes a dense mass between heavy castings until the mass disintegrates. It impacts and abrades material until it yields to the applied forces. It rumbles and vibrates and bangs as its core shaft spins eccentrically to capture and destroy chunks of stone.

These powerful, destructive forces take their toll on the machinery as well as the wear parts. Excessive wear and mechanical damage must be avoided, as downtime and reduced output quality are so costly. Regular checking and maintenance are essential to keep your crusher and your output in prime condition.

At the start of each day, give the crusher a quick visual inspection to check for potential issues. Evidence of an oil leak or excessive puddling of lubricant is a red flag. Lubricating and hydroset oil levels should rest at the correct level and the oil reservoir should be accessed without knocking contaminant into it. The oil strainer should be clear, conveyor and drive belts aligned and taut, and bolts tight.

A visual check on the pinion shaft housing for leakages, and a tactile check of its temperature, will reveal some of the problems that can occur. Material spillage under the machine may need to be addressed make sure residue does not find its way into components and contaminate lubrication. A daily morning walk-around establishes a good baseline for crusher performance.

Looking into the crushing chamber through the inspection hatches on the feed hopper is a simple way to identify non-crushable items that might have entered the crushing chamber. Any such items should be removed before operation, as they might affect or partially block the crushers intake. This will have a negative effect onthe performance of the machine and, in the worst case, could be the starting point for a breakdown.

Its advisable to spend a few minutes examining the concave and mantle through the bottom shell inspection hatches. This will reveal possible cracks or abnormal wear that might affect performance or lead to downtime.

After starting the crushers power plant, make sure the gauges are registering as the manufacturer recommends and that settings are correct for the material to be worked. Oil pressure should stay within acceptable limits. Idling the crusher during warm-up is acceptable but not for an extended period.

Some inspections are best made after the crusher is shut down. For example, a spider-bearing grease leakage may be visible on the main shaft sleeve after shut down. Some checks made at the end of the working day will not have to be duplicated the following morning.

This more thorough check builds on daily observations. An oil filter and tank may pass the end of day checks, but a more complete examination at the weeks end might show, for example, corrosive failure in an oil line. Liners and mantles that looked intact each day should be examined weekly for uneven wear, particularly when very abrasive material is being processed. Pinion shaft lubrication and gear backlash should be checked each week. The integrity of seals will be evident at the end of a weeks operation, and unaligned conveyor and drive belts will display unevenness.

A top to bottom inspection once a year or better still, every 2000 hours is best practice for maintenance. But remember that important inspection measures must be taken every time the crusher is opened, and intervention may be needed at earlier intervals.

In practice, relatively few cone crusher owners take the time for a thorough examination. However, there are many good opportunities for doing this. Changing out a liner, or performing an emergency repair, can require a crane. With the heavy lifting equipment already in place and operations already disrupted, this is a good time to dismantle a unit and look for issues such as worn sleeves and bushings, compromised seals and disintegrating hoses. Catching a failing component before it fails will prevent ancillary damage and unplanned downtime.

diamond mining solution - mineral processing

diamond mining solution - mineral processing

Commonly used beneficiation methods include gravity separation, flotation, magnetic separation, electrical separation and chemical beneficiation. Even the same type of copper ore, it is necessary to design the most appropriate process according to local conditions, and cannot be copied completely.

Crushing: cone crusher, improved cone crusher and high-pressure grinding roller (HPGR).Waste classification: NIR (near infrared) classification, optical (color) classification, XRF (X-ray fluorescence)Concentration is performed by combining dense medium separation (DMS) with XRT (transmitted X-ray), pulsed X-ray, mineral jigs according to application and condition.Using conventional X-ray technology, pulsed X-ray technology or XRT for the final recovery of diamonds.

Processing of diamond ores begins with crushing. Typically, an ore is crushed initially to below 250 mm by means of a gyratory crusher and then to 75 mm using a cone crusher. The final stage of crushing is done by means of a high-pressure roller mill to further reduce the size below 25 mm. The incremental size reduction is helpful for minimizing the possibility of breaking diamonds inadvertently. The crushed ore is scrubbed in a tumbler in the presence of water, while the fines generated during crushing and scrubbing are removed by screening typically at 2 mm. The crushed ore in the range of 225 mm size is sent to heavy-media cyclones, with the diamond-rich underflows going to X-ray sorters to recover diamonds. The reject streams from the X-ray sorters are then sent to grease tables (or belts), in which diamonds are retained on the grease table as they are selectively attracted to the grease via hydrophobic interaction while hydrophilic gangue minerals flow through.

In most cases, the materials smaller than 2 mm are disposed of without further processing due to the lack of appropriate separation methods. In some plants, the 2 mm material is screened at 0.5 mm, and the 2 + 0.5 mm fraction is subjected to flotation.However, it has been a challenge to recover small diamonds by flotation for two reasons. One is the difficulty in floating diamonds as large as 2 mm using conventional flotation machines. In general, mineral flotation is effective in the narrow particle size range of 0.10.25 mm. The other is that the dissolved species present in the aqueous phase of kimberlite ore slurry tends to reduce the hydrophobicity of diamonds, while the flotation of coarse particles requires stronger collectors that can increase the hydrophobicity beyond the level that is required for the flotation of smaller particles.

A horizontal rotating cylindrical drum with internal lifters that continuously abrade material under controlled water to ore ratios. Not applicable for plastic type clays, as these can pelletize through the tumbling action.

Disagglomeration for clay removal Abrasion resistant paddles affixed to a horizontally mounted rotating shaft yields an aggressive washing action that breaks down clay, it is more applicable to tough plastic type clays.
