In crushing, particles are reduced in size to such a level that grinding can be conducted, while grinding allows to achieve the desired liberation size. Besides, the process of comminution can be simple or complicated depending on the nature of the ore and the suitable degree of liberation.

Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on "run-of-mine" ore, while grinding (normally carried out after crushing) may be conducted on dry or slurried material. In comminution, the size reduction of particles is done by three types of forces: compression, impact and attrition.
