There are different types of crushers for different types of rocks and stones and different sizes of the input and output material. Each plant would incorporate one or several crushing machines depending on the required final material (small stones or sand). [1]
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.

Hoppers are rectangular or circular in cross section but have sides that slope at about a 60° angle.
