Sizing a crusher can be done reliably calculated thanks to the ImpactCrushing Work Index and the testwork research done by Fred Chester Bond and his 1952 paper. According to Bonds Third Theory of Comminution, the workenergy input is proportional to the new crack tip length created during particle breakage and equivalent to the work represented by the product the feed.

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.
