Impact Crusher Working Principle

22-06-2015  The procedure works quite well for this type of crusher but tends to understate power requirements in fine crushers where power rates are typically much higher (upwards from 0.25 KWH/tonne). Because of this, a research program was instituted by Allis-Chalmers Comminution Task Force Committee to break rock in a manner more analogous to that observed within commercial fine crushers.

Predicting the overall specific energy requirement of ...

01-05-2009  This lower energy requirement is confirmation of fundamental studies by Schonert (1991) on the relative energy efficiencies of different size reduction processes. It is pointed out that these figures represent the net specific energies of the size reduction equipment only and hence do not include ancillaries such as screens, conveyors, dust extraction systems and pumps.

Choosing the right crusher - Buying Guides

The cone crusher cannot take material of all sizes. The materials must be pre-dimensioned for the crusher (usually 200 mm or less). The finished product is not homogeneous, which is an essential requirement for many material specifications. Not suitable for handling clay or metal mixed with rock.
