Crushers are key equipment in mining, construction and aggregate industries. They break large rocks, ore, or other materials into smaller, more usable pieces. This equipment reduces the material by means of compressive force, impact, attrition or shear that are specific for the type of crusher being used.
IRON ORE C ONFERENCE PERTH, WA, 12 ˜ 14 AUGUST 2013 349 introduction Mining operations use crushers, commonly classified by the degree to which they fragment the starting material, with primary and secondary crushers handling coarse materials, and tertiary and quaternary crushers reducing ore particles to finer gradations.

Jaw crushers are used as primary crushers, or the first step in the process of reducing rock. They crush primarily by using compression. The rock is dropped between two rigid pieces of metal, one of which then moves inwards towards the rock, and the rock is crushed because it has a lower breaking point than the opposing metal piece.
