Most crushers used for aggregate production fall into one of three main categories/types: Compressive crushers which squeeze the material until it breaks. Impact crushers which use the principle of rapid impact to shatter the material. Attrition crushers which use both impact and grinding to shear the material.

The impact crusher is an explosion crusher that impacts and explodes material. The quality of the finished product does depend on one's perspective of exactly what the target is. If one's target is to produce fines, the impact crusher may be a better choice. If the target is a coarser blend of material, the jaw crusher may be best.
