· Most crushers used for aggregate production can be categorised as one of three main types: Compression crushers – which squeeze the material until it breaks. Impact crushers – which use the principle of rapid impact to shatter material. A ttrition crushers – which use both impact and grinding to shear material.

· Compared with compression crushing, impact crushing will create more fines within the circuit, which will cause greater wear if processing abrasive material. This is why rocks with lower silica content are more suited to reduction by impact crushers. When compared with cone crushers, impact crushers often have a lower capital cost, but can

Pros. Impact crushers are capable of delivering a much more homogenous, consistent and cubical end product. This makes impact crushers favourable when the final result needs to be a saleable commodity. Moreover, impact crushers can be highly efficient. They also use comparatively low energy compared with other crushers types.
