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.

In the makrket, two most popular aggregate crushing equipments include: Cone Crusher vs Jaw Crusher. Although the cone crusher and jaw crusher are used to crush materials, what is the difference between the two crushers?Table of Contents Jaw CrusherAdvantages of Jaw CrusherCone CrusherAdvantages of Cone CrusherWhats The Difference Between Jaw Crusher and Cone Crusher1. Different Working Principle2. Adapt To Different Material3. Different Feeding Method4. Different Final CostHow To Choose Right Crusher

Jaw crusher has a moving jaw plate and a fixed jaw plate, which are wear-resistant and pressure resistant. During the operation, the jaw plate simulates animal occlusion, and the feeding port is large, so it is very suitable to deal with the coarse crushing of large block materials;

Cone crusher, with various types, large processing capacity range, high efficiency, low energy consumption, uniform product size, which is suitable for medium and fine crushing of various ores and rocks.

Jaw Crusher: The crushing chamber of jaw crusher is composed of fixed jaw plate and movable jaw plate. The fixed jaw plate is fixed vertically on the fuselage body, and the movable jaw plate is in the inclined position. The movable jaw plate continuously moves to the fixed jaw plate periodically. When the two jaw plateare close, the material is crushed by extrusion. When the movable jaw plate is far away, the broken material slides down and is discharged from the crushing chamber.

Cone Crusher: The motor of the cone crusher drives the transmission shaft to drive the eccentric sleeve to rotate, and the movable cone swings back and forth under the force of the eccentric sleeve, the movable cone is periodically close to and far away from the fixed cone, and repeatedly extrudes and impacts the material until the material meeting the requirements falls to discharge from the crushing chamber.

The gyratory body of cone crusher is higher, twice or three times of jaw crusher, and the workshop cost is larger. The weight of cone crusher is larger than that of jaw crusher with the same output by 1-2 times, so the equipment cost is higher. The installation and maintenance of cone crusher is more complicated than jaw crusher.

Therefore, when crushing hard rocks and long rocks, the cone crusher should be preferred. This design is more favorable. When wet and viscous ore is crushed, or medium, small concentrators, jaw crushers are suitable.

The weight of cone crusher with the same output is about twice that of jaw crusher, so the cost of civil engineering and later maintenance is higher, but the cone crusher has deep crushing cavity, large capacity and low energy consumption.

All the heavy machine manufacturing in India has led to its development in the past. There are many heavy types of machinery manufactures in the country which has earned credits all around the globe. There are Jaw crushers manufacturers in India, as well as there are cone crusher manufacturers in India.

These machines are used majorly in the field of construction, metallurgy, chemical and silicate industry, mining, and road building. Its a no-brainer that the both these machines, i.e. the jaw crusher and the cone crushers find their utility in the crushing process.

A layman is ought to use the names for these machines alternatively, but there are many differences between the two popular machines. Let us walk through a comparative analysis between the cone crusher and the jaw crusher.

A Jaw crusher is made up of two jaws- the fixed one and the moving one. The machine is used to crush larger sized rocks in a motion resembling that of a nutcracker. The crushing process reduces the size of the stones. The chute that filters the rocks is built in such a way that it narrows towards the base. This helps in filtering the rocks and allows only a particular size of rocks to pass through.

A cone crushers components that is the fixed and the movable cones are similar to that of a jaw crusher. The major operational difference is that the cone crusher utilizes both the cones to grind ores and rocks into smaller pieces. The input is fed in between the two cones and the output is discharged from the discharge hole at the bottom of the cones.

A cone crusher, on the other hand, operated on the principle of rotating oscillatory motion. The pressure on the stones acts when in between the two cones. The two cones do the eccentric swinging movement and produce a force strong enough to crush the hard rocks. The bending force, shearing force and friction force result into a strong force which ultimately breaks the rocks.

A cone crusher is used for secondary crushing. The input to the cone crusher is much smaller and fragmented than that in the jaw crusher. The granularity of the materials that are crushed in the cone crushers is about 35mm to 350 mm. A cone crusher is best suitable for crushing of materials with high hardness like granite, marble, pebbles, dolomite, rhyolite, and diabase.

A Jaw crusher is used in the fields of quarrying, mining, recycling, infrastructure, and construction. It plays the primary role in the crushing of huge stones. Some of the features of the Jaw crushers are:

cone crusher vs gyratory crusher - jxsc mine

{Cone Crusher vs Gyratory Crusher}Both cone and gyratory crushers have a cone, and their outline that looks have a little resemblance. The two crushers can continuous working, and their working principle in the same way. But the cone crusher vs gyratory crusher, their structure and performances are different.

The cone liners of the gyratory crusher are steeply inclined. The movable cone that up part is small and lower structure is large, while the fixed cone in which the top is big and the bottom is small. Therefore, it can increase ore feeding capacity. The cone of cone crusher is gently inclined, and the movable cone and fixed cone are placed in the truncated cone. There is a certain length of parallel ore crushing zone between the two parts, which can better control the size of ore discharge. Under the action of the high rotating speed movable cone, the ore is guaranteed to be crushed at least once in the parallel zone. As a result, the product has a uniform particle size.

The movable cone of the gyratory crusher is suspended on the crossbeam, and the movable cone of the cone crusher is supported on the spherical bearing. If it also uses suspension structure which will affect the uniform feeding. The dust-proof device of the cone crusher is more strict, and the water seal dust-proof device is often used.

The discharge gate of the gyratory crusher is large, so the size of the small non-broken things such as hammer allowed through. There isnt much required in its safety device. But the cone crusher must be equipped with a safety device, and the requirements of reliable work. A precompression spring safety device or a hydraulic safety device is usually used.

There is hardly any effect that the gyratory crusher because of the liner wore to make the discharging ore increases little. Therefore, it is usually used to adjust the size of the outlet by moving the cone up or down. Cone crushers require the uniform size of ore discharge, and the scope of increasing the size of ore discharge is very small because of the wear of the lining plate. Because the ore discharge opening is frequently adjusted, the adjusting device is required to be easy to operate. For example, a spring cone crusher can adjust the height of the fixed cone to change the size of the outlet. It should be noted that since the introduction of hydraulic adjustment and hydraulic insurance, the adjustment mode of the gyratory crusher and cone crusher is not very different. Jaw Crusher VS Gyratory Crusher

1. The rotating speed of the movable cone of the gyratory crusher is low, the stroke is small. And the ore is mainly crushed and broken and bent. The cone crusher has 2.5 times higher rotating speed and 4 times larger swinging angle than the gyratory crusher, so the ore is impacted quickly. Therefore, it is advantageous to the ore crushing, the crushing efficiency is high.

2. Different applications. In large quarries, gyratory crushers are often used as primary crushers. But the cone crusher is used as secondary and tertiary crushing more often and often used in sand plants and mines.

The cone crusher has the characteristics of high efficiency, high crushing ratio, low power consumption, and uniform product. So, since the end of the last century, it has been widely used in the world. And the crushers are constantly improvement and perfection on its itself structure. Cone crusher is suitable for medium and fine crushing of materials of various hardness.

cone crusher vs. impact crusher | quarrying & aggregates

Not every crusher is suitable for every application. When choosing the best crusher for aggregate applications, it is important to understand how the crusher works and its impact on efficiency, operating costs and final products. When designing aggregate processing production line plans, there are usually differences in the choice of impact and cone crusher. What is the difference between impact crusher and cone crusher? Which is the best fine crushing equipment?

For impact crusher, the high-speed rotating rotor throw stone into impact plates, stones are crushed via impact energy produced rotating rotor. So, impact crusher is good to crush soft material of brittle stone.

Initial High-manganese steel is softer than high-chrome steel, but high-manganese steel has features of high tenacity, that means after many times strike and crushing stone, this high-manganese steel will become harder and harder, so, high-manganese steel is usually used to crush hard stone, and its service life will be very long. So, both jaw plates of jaw crusher and bowl liner & mantle of cone crusher are made from high-manganese steel.

High chromium iron is very hard, but it is a little brittle, so, it usually used to crush soft material like lime stone. Therefore, the most common blow bar/hammer material of impact crusher is high chromium iron.

According to our experience in Zambia and Nigeria, most of the local raw materials are hard stones like granite, so most investors or equipment owners in Zambia and Nigeria usually use cone crushers as secondary crushers. Because of its high production efficiency and low maintenance costs for hard stones.

Due to the different types, sizes and uses of stone crushers, and the large investment required to purchase stone crushers, it will make the purchase of equipment difficult. When you are looking for crushers or other aggregate equipment, please contact our aggregate equipment experts to help you make the right choice in the first time.

Do you need to process sand, gravel, minerals, rock, or other aggregate products and have not yet purchased or leased crushing equipment? Theres no questionyou need to work with a capable and professional material handling equipment design and engineering company dedicated to selling, renting, and installing the best new crushers for your needs.

However, if youre new to the aggregate processing industry, you probably have a lot of questions about rock crushers. As foundational material handling equipment in all plants, crushers need to coordinate seamlessly with screens, conveyor systems, and washing equipment.

It is common to use multiple crusher types within a project and set them up as stations in a circuit format to perform the necessary material reduction work. In many cases, primary, secondary, and tertiary, and quaternary stations are installed to reduce the rock to the desired size, shape, and consistency.

For instance, if the final size of your product only needs to be between 4 inches and 6 inches, a primary jaw or impact crusher can accomplish your goals. However, you will likely require a much finer product, and that means incorporating up to threeor even fourstations with a variety of crusher types.

As the first stage in a crushing circuit following extraction from a mine site, (or in the case of recycled asphalt production, delivery to the RAP processing plant via truck transport), primary crushing reduces material to a size and shape that can be handled by the secondary crusher.

Typically, the minimum setting on most primary crushers will be about 4 to 6 inches, as noted above. Compression-style jaw, cone, impact crushers, and gyratory crushers are most often appropriate as primary crushing equipment types, though there can be overlap between primary and secondary crushers as far as suitable types.

In secondary crushing, reduction ratios become an essential consideration. Knowing just how fine you need your final output to be, along with the feed requirements of your tertiary or final reduction crushing station, will help you determine how much reduction needs to take place within this stage.

Cone crushers are often placed within the secondary crushing station because they are versatile in terms of feed, closed side setting, speed, and throw. With cone crushers, though, it is essential to operate them at consistent choked settings to keep productivity up.

The goal of the tertiary (third), quaternary (fourth) or final reduction stage of the crushing process is to size and shape rock or other material into a marketable product. Again, there may be overlap between stages in terms of which crusher styles work best.

Sandstone, limestone, gravel, and granite are arguably the most common aggregates used in the construction industry today, but these rocks have very different hardness and abrasiveness characteristics.

The answer might be three to four if youre talking about setting up stations in a complete rock crushing plant. Those are the primary, secondary, and tertiary/quaternary/final reduction rock crushers, which we covered above.

Of course, there are also different styles of rock crushers. Compression-style jaw and cone crushers, for example, fit into the various stations in a crushing circuit (depending on factors like the sizes, varieties, and hardness of the rock you need to crush, as well as the necessary output).

The number of crusher types in terms of style and configuration can be more challenging to quantify, as there are lots of ways to customize rock crushers. However, youll find four basic designscone, jaw, gyratory, and impact crushersoperating within many crushing plants.

Jaw crushers are also known as rock breakers and are used to break up larger, harder materials into more manageable pieces. They tend to do well with many different types of materials and dont display as much wear and tear as impact-style rock crushers. They also produce minimal fine materials and dust, though the finished product with this type of rock crusher almost always requires secondary crushing.

To learn more about jaw crushers, youll want to catch our previous blog post all about these tough pieces of material handling equipment and the most common questions operators have about jaw crushers.

Cone crushers can accept medium-hard to very hard and abrasive feeds that might be dry or wet, though not sticky (whereas gyratory crushers are better at handling softer, dryer feeds). Their output will be a relatively cubical product, with a reduction ratio of about 6-to-1 through 4-to-1.

Impact-style crushers include VSIs, as well as horizontal shaft impactors (HSIs), and are best used with less abrasive rock types, like limestone. These types of machines break apart material by the impacting forces of certain wear parts known as blow bars and impact plates or toggles.

Some operations also use impact-style crushers after they have already used a different type of rock crusher that produces a more elongated stone. This helps further shape the crushed material into a finer consistency with a more cubical nature.

Impact crushers tend to be less expensive than compression crushers (aka cone and jaw crushers, which we already covered) and have a higher reduction ratio. They can also break sedimentary deposit-type rockslimestone and similaralong natural lines, which rounds off sharp angles and weak edges. This can produce a result that is more sand-like in nature.

Drawbacks of impact crushers include their tendency to produce an excess of fine materials if used with softer rocks. Impact rock crushers can also require frequent part changes and can create a large amount of dust that can be an issue on some worksites.

Stationary plants have long been preferred because they feature a higher capacity and efficiency and lower production costs with easier maintenance. They also have historically featured a lower energy cost if you have on-site electricity, and no additional equipment is needed to move them from place to place.

Its true that portable material handling equipment already offers unmatched production flexibility. For instance, if you need to move your crushing plant more than once a year to multiple job sites, you are likely better off investing in portable equipment.

These self-contained plants are better suited to smaller projects and can be moved from project to project as necessary. They are often still not quite as efficient and have less capacity than stationary plants, but they can be more cost-effective in the long run if you have multiple projects in different areas.

compare gyratory crusher vs jaw crusher

compare gyratory crusher vs jaw crusher

To accomplish this reduction in size takes several steps or stages of crushing and grinding. Primary crushing is the first of these stages. Generally speaking there are two types of primary crushers, lets compare them: GYRATORY CRUSHER or a JAW CRUSHER. Although they dont look anything like they do have similarities that put them into the same class of crusher.

Their CRUSHING SPEEDS are the same, 100 to 200 revolutions per minute. They both break the ore by COMPRESSION. That is they both break the rock by squeezing it until it breaks. On the average their final product will measure about seven inches at its widest point. And finally they both can be built to accept a rock up to sixty inches across.

Even if they are much alike, each of the two types of crushers has its own uniqueness. Because of this difference each type of crusher has its own environment that it operates best or at least better in, than the other.As an example, a gyratory crusher can be fed from two sides and handle ore that tends to slab. Also its design allows a higher speed motor with a high reduction ratio between the motor and the crushing surface. This is an important consideration as it means money saved in energy costs. A jaw crusher on the other hand requires a flywheel to store energy but can be used on the tougher ores due to its box frame construction. To be effective it must be fed from one side only but it handles square block-like ore well.

There is another comparison that should be taken into consideration, that is the amount of space that each takes. The Jaw crusher is the smaller of the two and its single feed point will make it a logical choice for underground workings. In the actual operation of the crushers, they both have similarities as well as differences so lets take each one separately and discuss its design and its problems. Considering the title of this chapter is Primary Crushing (Gyratory) we should discuss that one first.

In the introduction I mentioned that the purpose of a concentrator was to produce a concentrate of which ever mineral was being mined. To be able to recover this mineral it is necessary to reduce the ore in size until the mineral is LIBERATED. This means that the ore must be reduced in size until it is fine enough to be able to separate the mineral from the unwanted rock. In the Vocabulary of the metallurgist, at this point of the operation the unwanted rock will be termed the GANGUE material. You will notice that the terminology used for the ore will change depending upon the stage of concentration. The reason for this is to keep technical communication accurate.

The size requirement of the primary rock crusher is a function of grizzly openings, ore chute configuration, required throughput, ore moisture, and other factors. Usually, primary crushers are sized by the ability to accept the largest expected ore fragment. Jaw crushers are usually preferred as primary crushers in small installations due to the inherent mechanical simplicity and ease of operation of these machines. Additionally, jaw crushers wearing parts are relatively uncomplicated castings and tend to cost less per unit weight of metal than more complicated gyratory crusher castings. The primary crusher must be designed so that adequate surge capacity is present beneath the crusher. An ore stockpile after primary crushing is desirable but is not always possible to include in a compact design.

Many times the single heaviest equipment item in the entire plant is the primary crusher mainframe. The ability to transport the crusher main frame sometimes limits crusher size, particularly in remote locations having limited accessibility.

In a smaller installation, the crushing plant should be designed with the minimum number of required equipment items. Usually, a crushing plant that can process 1000s of metric tons per operating day will consist of a single primary crusher, a single screen, a single secondary cone crusher, and associated conveyor belts. The discharge from both primary and secondary crushers is directed to the screen. Screen oversize serves as feed to the secondary crusher while screen undersize is the finished product. For throughputs of 500 to 1,000 metric tons per operating day (usually 2 shifts), a closed circuit tertiary cone crusher is usually added to the crushing circuit outlined above. This approach, with the addition of a duplicate screen associated with the tertiary cone crusher, has proven to be effective even on ores having relatively high moisture contents. Provided screen decks are correctly selected, the moist fine material in the incoming ore tends to be removed in the screening stages and therefore does not enter into subsequent crushing units.

All crusher cavities and major ore transfer points should be equipped with a jib-type crane or hydraulic rock tongs to facilitate the removal of chokes. In addition, secondary crushers must be protected from tramp iron by suspended magnets or magnetic head pulleys. The location of these magnets should be such that recycling of magnetic material back into the system is not possible.

Crushing plants for the tonnages indicated may be considered to be standardized. It is not prudent to spend money researching crusher abrasion indices or determining operating kilowatt consumptions for the required particle size reduction in a proposed small crushing plant. Crushing installations usually are operated to produce the required mill tonnage at a specified size distribution under conditions of varying ore hardness by the variation of the number of operating hours per day. It is normal practice to generously size a small crushing plant so that the daily design crushing tonnage can be produced in one, or at most two, operating shifts per working day.
