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.
