Comminution - Wikipedia
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 industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields Bond, F.C. The third theory of comminution.
