Gyratory and Cone Crusher ScienceDirect

5.6. Power Consumption of Gyratory and Cone Crushers. To compute the power consumption of gyratory crushers, knowledge of the ore work index and crusher capacity is necessary. In its simplest form, the power consumption is given by (5.5) P = W i Q F 80 − P 80 F 80 100 P 80 where P = power (kW) W i = work index (kWh/t) Q = capacity (t/h)

Crusher Wikipedia

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.

Gyratory Crusher an overview ScienceDirect Topics

A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening. Hammer crushers are used either as a one-step primary crusher or as a secondary crusher for products from a primary crusher.
