Jaw Crusher is a kind of stone crusher, which is also called rock crusher. It is widely used in many fields, such as mining, smelt metal, building materials, public road, railway, water conservation, chemical industry, and so on. Each crusher is designed to work with a certain maximum size of raw material, and often delivers its output to a screening machine which separates the products into several types for further processing.
Typically, crushing stages are followed by milling stages if the materials need to be further grinded. Stone crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder.
