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 … See more The comminution of solid materials consumes energy, which is being used to break up the solid into smaller pieces. The comminution energy can be estimated by: • Rittinger's law, which assumes that the energy consumed … See more • Mill (grinding) – Device that breaks solid materials into smaller pieces by grinding, crushing, or cutting • Particle size distribution – Function representing relative sizes of particles in a system • Crusher – Machine designed to reduce large objects into smaller ones See more There are three forces which typically are used to effect the comminution of particles: impact, shear, and compression. See more There are several methods of comminution. Comminution of solid materials requires different types of crushers See more
