Crushing Equipment, Crushing Mining Equipment
Crushing Equipment Types. All crushing equipment can be divided into two main categories. Compression mining crushing equipment apply pressure to the material until it is broken, and impact crushers utilize the principle of rapid impact to break the material. Jaw crushers, gyratory crushers and cone crushers operate on the compression principle.
