all you need to know about crusher liner wear simulation

Crushing machines are used to reduce the size of large rocks into small rocks, sand, gravel, or rock dust. These machines hold feed material between two tangent or parallel solid surfaces and apply adequate force to move the surfaces. The surfaces come closer and crush everything between the two them.

There are different types of crushers available in the market that vary based on their working capability. Some of them are used for primary purpose crushing and others are used for secondary crushing. Similarly, a few crushers are available for tertiary and some for the fourth level of crushing.

Crushers work based on different principles. For example, jaw, cone, and gyratory crushers work based on compression. On the other hand, cutter mills and hammer crushers work based on shear and impact principles respectively.

All crushers come with different types of liners. Similarly, each crusher contains a variety of liners like jaw crusher comes with square tooth liner, wide teeth liners, and coarse corrugated liners, etc. Further, the working mechanism of each liner varies based on its type and crushers.

This article explains the complete crusher liner wear simulation. There are plenty of crushers available in the market. So we cant cover all the liners of crushers in this article. Therefore, we will only discuss a few renowned crusher liner wear simulation. Lets get started

We are selectively explaining the simulation of the 3 most popular crushers liner wear. Jaw and Gyrator crushers are the primary purposes of crushing machines. And, cone crusher is a secondary crushing machine. However, you can use it for primary crushing as well. Lets dive deeper and explore the liner wear simulation of these machines:

Jaw crusher is a primary purpose crushing machine that contains two jaws i.e. stationary and moving jaw. Stationary jaw remains fixed and the moving jaw moves back and forth relative to the stationary jaw. Each jaw contains a liner that is made of manganese steel. These are hard enough to crush the stone and abrasive materials.

The crushing chamber is an area between the two jaws from where crushers receive the feeding material. Swing jaw moves slightly and applies pressure on the rock. Crushing is performed gradually rather than in a single stroke.

The power that moves the jaw comes from the flywheel. The flywheel produces an eccentric motion so that the swing jaw moves back and forth for crushing the object. Both jaws make an acute angle so that the moving jaw moves around the pivot and makes a strong impact on a fixed jaw. As a result, the object between the two jaws turns into small pieces.

It is another most popular type of crusher used for secondary crushing. The major use of cone crusher is in the aggregate, fracking sand, coal, and mining industries. It is a compression-based crusher that squeezes or compresses the objects until they break.

Cone crusher contains two pieces of steel i.e. an eccentrically rotating and stationary piece of steel. The eccentrically rotating piece is known as the mantle and the stationary part is called a bowl. Both parts contain liner wear that actually breaks the hardest rocks.

The area between both parts is called the crushing chamber. You need to place the material in the crushing chamber and it compresses that material between eccentrically rotating and stationary parts. Due to the compression, the material gets smaller and discharge at the bottom of the machine.

The size of the final yield is determined by the gap of both liners. So you can obtain the size of rock according to your need. The main purpose of cone crushers is to crush medium-harness or harder ores or rocks.

A gyratory crusher is another most popular primary rock crushing machine. The working mechanism of the gyrator crusher is almost similar to the jaw crusher. However, the only difference is that it comes with a circular gap. The circular gap is an area between a static conical bowl and a concave mantle.

As the name suggests, the static conical bowl is a fixed area but concave mantle oscillates about the central axis. Both parts have an extremely strong liner that is designed to crush the most abrasive rocks. The main purpose of the gyratory crusher is to perform large-scale rock crushing up to 6000 t/h.

You might be thinking that what is the difference between cone and gyrator crusher. Because both crushers have many similar things. For example, both use a cone-shaped crushing surface and also work on the same crushing principle. So what is the difference?

The first difference between the two is that the gyratory crusher is a primary crushing machine however the other one is a secondary crushing machine. Second, both have different speeds of mantle i.e. gyrators mantle revolves 100 to 200 but cone crushers mantle revolves 500 to 600 RPM.

The other most noticeable difference is the crushing action of the mantle in both crushers. For example, gyratory crushers have all the movement at the bottom of the mantle due to its small angle. However, cone crushers have a greater angle that puts the pivot point below the distributing plate.

We have discussed the three main types of crusher liner wear simulation in this article. There are some other poplar crushers also available in the market like hammer crushers. These crushers have different liner wear simulation. So you should consider a crusher based on your primary or secondary need.
