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 ().
Manufacturing energy consumption includes fuel and nonfuel sources. Manufacturers consume two general types of energy sources—fuel and nonfuel.Fuel consumption is the use of combustible energy sources to produce heat and/or to generate electricity (which, by manufacturers, is mostly for their own use), and the use of electricity to operate equipment and associated manufacturing facilities.
