Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earth's crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with many types of mill. .

operational costs, with low energy efficiencies. Comminution accounts for 35 to 70% of the total energy requirement for mineral processing. The high energy requirements and cost involve in fine and ultrafine grinding are a major bottleneck on the economic potential for developing and operating a low grade magnetite deposits.
