MODELING OF THE PROCESS OF COAL GRINDING
of the grinding process is very difﬁ cult. In many in-stances, statistical theories are therefore used . In this paper, the Maxwell-Boltzmann statistics is used for the description of the grain size distribution in the grinding process. The effect of grinding is dependent, e.g., on the en-ergy supplied to the material particle being ground,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 ().3 Technologies in Exploration, Mining, and Processing,,Dry grinding, a higher cost process than wet grinding, is used mainly for downstream processing that requires a dry ground material or for producing a special dry product. The manner in which rock is blasted in mining operations subjects the rock mass to stress resulting in breakage.
