selection of secondary and reduction crushers

How it Works: Crushers, Grinding Mills and Pulverizers

Industrial crushers reduce large rocks, ore or waste materials to smaller sizes by impact or pressure to fracture or deform the material. During the primary crushing operation, boulder size feeds from 20 to 100 in. are reduced to secondary crusher sizes of 1 to 20 in. or mill feed size of .5 to 3 in.
