Automatic Electric Mild Steel Laboratory Jaw Crusher

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust for the lab testing purpose. 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
