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 composition can be differentiated.

Cone Crusher

For finer crushing or reduction a cone crusher the norm. are commonly used for secondary, tertiary or quaternary crushing. They do this by a different chamber design which is flatter and by operating at about twice the rotational speed of a primary type gyratory crusher.
