Tips for maintaining efficiency in crushing circuits

 · Size reduction in an impact crusher relies on energy being conveyed into the rock from the rotor, and it begins with your feed. The initial impact is responsible for more than 60 per cent of the crushing action, with the remainder made up of impact against an adjustable breaker bar and a small amount of inter-particle collision.

 · The energy in this case required to produce rupture will be the product of the average resistance to shearing per square inch by the area along which rupture takes place, and by the distance the two offset faces move together. The average resistance to shearing is a variable quantity, as the deformation increases up to rupture.

C R U S H I N G 8 Energy and Size Reduction The concepts of Work Index and Specific Energy make it clear that a certain (calculable) amount of energy is required to break a rock from one size to another. Experience has shown that to break a rock from coarse and medium size should require less energy per unit mass than to break a rock from coarse to fine, i.e. the smaller you want to break a.

Energy Required To Break Rock By Percussive Drilling

The energy transferred to rock (K x W) is partly transmitted further as elastic energy causing no fracturing and partly used to produce fracture at the end of the drill hole under the drill bit. If the energy required to produce unit volume of new hole is obtained from the crater experiments it includes both elastic and fracture causing parts of the energy transferred to rock.

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.
