The energy efficiency of ball milling in comminution. In his 1986 paper, ert provided a definition of process efficiency based on single-particle crushing data, namely, relating energy consumption in the ball mill to that consumed in single-particle crushing to yield the same particle size distribution as the mill product.

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 ().
