Selecting the right type of crushing equipment
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.
