Crushing Theory. Crushing Theory • When solid particles of feed material are being reduced in size, they are first distorted by straining and mechanical energy is stored in the solid in a similar manner to energy stored in a coil spring. • As more energy is applied, the material is distorted beyond their ultimate strength, thus causing them to rupture and thereby creating new surface.

tumbling mills. These contain a charge of loose crushing bodies-the grinding medium-which is free to move inside the mill, thus comminuting the ore particles. The grinding medium may be steel rods, or balls, hard rock, or, in some cases, the ore itself. In the grinding process, particles between 5 and 250 nun are reduced in size to

Rock Crushing Theory and Formula using Kick & Rittinger's Law
"The work done in crushing is proportional to the surface exposed by the operation; or, better expressed for this purpose, the work done on a given mass of rock is proportional to the reciprocal of the diameter of the final product, assuming that all the mass has been reduced to one exact size, which is only theoretically possible."
Mill (grinding) - Wikipedia
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
