Large-scale crushing operations are generally performed by mechanically operated equipment such as jaw crushers, gyratory crusher and roll crushers. For very large ore pieces that are too big for receiving hoppers of mechanically driven crushers, percussion rock breakers or similar tools are used to break them down to size.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand 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.

However, some jaw crushers employ attrition as well as compression and are not suitable for abrasive rock since the rubbing action accentuates the wear on crushing surfaces. As a mechanical reduction method, compression should
