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.
Product of each 20 by 15 is divided, going to two 30 by 5s. Product of 30 by 5s is elevated and screened; that passing a ¼ inch round hole is finished product, as far as crushing is concerned, and is carried to the jigs. The " coarse," 1½ to ¼ inch, goes to three 60 by 2 Multiple Crushers, each with three jaw openings 20 by 2 inches.
