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.

· If cone crusher maintenance is neglected, the result will be a detrimental effect on productivity and an overall higher energy cost per ton of material crushed. It’s not uncommon that aggregate producers’ maintenance teams are not fully aware of the maintenance requirements of a cone crusher or its impact on energy consumption.

13.3.1.1 Primary Crusher. Primary crushers are heavy-duty rugged machines used to crush ROM ore of (−) 1.5 m size. These large-sized ores are reduced at the primary crushing stage for an output product dimension of 10–20 cm. The common primary crushers are of jaw and gyratory types.

· Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.
