What is a crusher and crusher classification?

As we all know, crusher machines play important role in mining undystry. These crusher machines include jaw crusher,impact crusher ,cone crusher,hammer crusher, single stage hammer crusher, reversible hammer crusher and so on. Then what is a crusher? Now you can get the answer from this article.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly, and resist deformation more, than those in the material being crushed do. Crushing devices hold material between two parallel or tangent solid surfaces, and apply sufficient force to bring the surfaces together to generate enough energy within the material being crushed so that its molecules separate from (fracturing), or change alignment in relation to (deformation), each other. The earliest crushers were hand-held stones, where the weight of the stone provided a boost to muscle power, used against a stone anvil. Querns and mortars are types of these crushing devices.

Based on the crusher concept,then we will tell something about crusher classfication:

Crusher in accordance with the major categories can be divided into medical crusher and mining crushers. Which medical crusher is mainly used for stone crushing, general resonance stones broken, avoid surgical bring all kinds of risks; mining crusher is commonly known as crusher (broken equipment), mainly on the various types of stone crushing, broken principle and product particle size, is divided into many models.

The crusher is widely used in many sectors of mining, smelting, building material, highway, railway, water conservancy and chemical industry. Commonly used gravel mechanical jaw crusher, impact crusher, vertical shaft impact crusher, hydraulic cone crusher, ring hammer crusher, hammer crusher, roll crusher, compound crusher and so on.

So many crusher machines, how to select the right crusher machines for ore crushing? You had better send your requirements to the seller, he or she can offer you the suitable crusher machines according the raw materials that will be crushed, and the input size,the ourput size and the product capacity requirements.

Introduce you detail process about granite processing plant

Introduction about Granite

Granite is a kind of igneous rock and is shaped from magma. In general, granite intrusions are placed in the crust, and located about 1.5 to 50km depth within thick continental crust. Granite is not easy to be weathered and it has beautiful color. Granite appearance and color can be maintained for more than a century. Because high hardness and wear resistance, granite often use for senior architectural engineering. In addition, granite is also the first choice of the material of open-air sculpture.

Granite mining is a large industrial process which begins with exposing a granite deposit. Once the granite deposit is exposed open cast mining is the usual way to exploit the reserves. Granite is then extracted from the mine which is in itself a difficult process. Granite is usually drilled then hammered to separate individual blocks which are then lifted to the surface of the mine with cairns to be transported to a nearby processing plant.

The Process of Granite Crushing Plant:

Granite mill is used for further crushing-grinding. Raw granite rocks are feed into granite crusher (such as jaw crusher, granite crusher) continuously and evenly by vibrating feeder.


Granite processing uses jaw crusher as primary crusher. Then big granite ore change into relatively small stone. Through belt conveyor, these crushed granite ore are into cone crusher. Next procedure you can choose impact crusher as shaping machine according specific situation. In this granite processing plant, vibrating feeder and vibrating screen are also needed. Besides, belt conveyor is very important, because it plays a role in connecting the various parts. Overall, granite processing plant use machines such as vibrating feeder, jaw crusher, cone crusher, impact crusher, vibrating screen and belt conveyor.

The Solutions about the granite complete crushing plant:

Proposal 1: vibrating feeder + primary jaw crusher + secondary impact crusher + vibrating screen + belt conveying system + control system

Proposal 2: vibrating feeder + primary jaw crusher + fineness jaw crusher + impact crusher(optional)+ vibrating screen + belt conveying system +control system

Proposal 3: vibrating feeder +primary jaw crusher + cone crusher + fine impact crusher(optional)+ vibrating screen + belt conveying system + control system

In the above proposals, the main difference is the secondary crusher: using impact crusher, or using fineness jaw crusher, or Compound cone crusher. According to the fineness of the finished products, choose the right crushing machine.

We can provide granite crushing machines, screening machines, conveyor machines and feeder machines for granite processing plant, you can contact us online to get more information.
