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.
The major products are: R-pendulum grinding mill, raymond mill(grinder), high pressure suspension grinding mill, medium speed trapezium mill, super thin mill, straight centrifugal mill, jaw crusher, impact crusher, cone crusher, symons cone crusher, vertical shaft impact crusher, sand making machine, vibrating screen, vibrating feeder, sand washing machine, belt conveyor, mobile crusher,portable crusher etc. Especially, the high pressure suspension grinding mill YGM 9517 and PCL vertical shaft impact have won the honor of Shanghai high technology conversion effort.
