A highquality hammer crusher can keep final material passing a twenty mesh, fifty to sixty percent passing a fiftymesh screen. Crusher hammers are high chrome content. The hammer service life depends on the material you process. If you're running abrasive quartz, they'll last somewhere between one to two weeks.

In conventional mining, doubleroll crushers are sometimes referred to as "mineral sizers" since they reduce the size of the largest chunks without pulverizing the smaller particles. These types of crushers or sizers are commonly used in reducing the topsize of soft or sticky material, such as limestone or lignite (brown coal).

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.

Crushers are also classified by their method of mechanically transmitted fracturing energy to the material. Jaw, gyratory and roll crushers work by applying compressive forces while impact crushers such as hammer crusher apply high speed impact force to accomplish fracturing. There are several types of crushers which are used in various industries.

The processing system of the doubletoothed roller crusher makes it possible to crush any type of raw material from hard (limestone and rock) to soft (clay, soil and mud) or even elasticlike wood or rubber tyres. The rotation speed, especially if compared to traditional crushers, is very low; so low, in fact, that tip speed is under 3 m/s.
