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.Crushing machine is widely applied in many industries such as mining, metallurgy, construction, Highway, Railway, water conservancy and chemicals production. The current widely used crushing machinery are jaw crusher, impact crusher, Vertical shaft impact crusher, hammer crusher, roller crusher and combination crusher, etc. Our crushing machines are relatively more efficient and reliable compared to others. Because we enjoy a 30 years' experience in this field. And every year, we use 15% of our profit to do the research and development of new products. Our quality and innovation are both at the top of this industry.
