In crushers the energy is applied directly to the ore particles in tumbling mills the energy is directed into rotating the mill and its charge and size reduction occurs as consequence of this motion. In crushers the crushing elements are fixed with relation to one another whereas in grinding mills the crushing elements are free and are held apart from one another only by the ore which is being ground between them 17

· Crushing and Grinding. Crushing is the first mechanical stage in the process of comminution in which the main objective is the liberation of the valuable minerals from the gangue. In the nature minerals are usually intergrowth with other mineral species. In order to separate them they must be unlocked through comminution (crushing and grinding).
