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. Jaw crushers, cone crushers, gyratory crushers and roll crushers all operate on the compression principle.
