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 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

particle size. Lab tests show that the particle size achieved from a bead mill is a direct function of the media size used in grinding. One rule of thumb is that the average particle size quickly achievable in a bead mill is about 1/1000th the size of the grinding media. Graph 2 illustrates this point: We see that rapid particle size reduction
Particle Analysis in Mining and Minerals - HORIBA
Many of the particles encountered in mining are characterized by sieves (classifiers). Recent advances in computers, cameras, and software make image analysis practical for samples with sizes larger than several microns in diameter. As particle size decreases, sieving and/or dynamic image analysis becomes more arduous or impossible and laser diffraction becomes the technique of choice.
The size reduction theories of solid foods
Three types of force are used to reduce the size of foods: compression forces, impact forces and shearing (or attrition) forces.
