Impact (rotary and hammer) crushers are designed for impact crushing of various brittle materials using beaters rigidly fixed to a rotor rotating around a horizontal axis [7], while destruction occurs due to splitting. The destruction of brittle rocks by impact and compression requires different energy

Hammer force refers to the force exerted by a hammer on an object when it is used to strike. This force is a result of the hammer's mass and its acceleration at the moment of impact. Hammer force, HF (N) in Newtons is calculated by multiplying the mass, m (kg) in kilograms by the acceleration due to gravity, a (m/s2) in metres per second squared.

— The springs are helical and pressure varies with the size of crusher and could be as high as 6 t/m (about 8300 kPa). In some roll crushers the rolls are individually driven. The drive is either by gears or belt. Both rolls usually rotate at the same speed but some crushers are designed such that one roll could rotate faster than the other.
