Crusher - Wikipedia
Crusher. 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 ...

Gyratory Crusher - an overview ScienceDirect Topics
Jaw and gyratory crushers are used for initial size reduction to convert big rocks into small stones. This is generally followed by a cone crusher. A combination of rod mill and ball mills are then used if the ore must be ground below 325 mesh (45 μm). Instead of grinding the ore dry, slurry is used as feed for rod or ball mills, to avoid dusting.
