Crushing 101 | Masaba - Masaba Inc.

8:1 maximum reduction ratio for compression crushing, this is normally used as a primary crusher. Jaws perform well in many materials. Yields low wear cost per ton in hard abrasive deposits, minimal fines but produces little finished (under 1”) product which places more load on the crushers downstream in the circuit.

Crusher - Wikipedia

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.
