concerned with the energy intensity of this process, while the second one with the determination of the grain size distribution of the grinding product. The study of the energy intensity of the grinding process is very im-portant, because energy intensity is the main measure of the process costs. Thus, it is the criterion for the cost-
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 (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
