The low efficiency of grinding equipment in terms of the energy actually used to break the ore particles is a common feature of all types of mills, but there are substantial differences between various designs. Some machines are constructed in such a way that much energy is absorbed in the component parts and is not available for breaking.

The comminution process reduces particle sizes by breaking, crushing, or grinding of ore, rock, coal, or other materials. The process is most often used in the field of mining and / or mineral processing, where mineral ore is broken down into small particles, by hammer, roller / vibrating disc mills and jaw, gyratory and cone crushers.
