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 ().
Ball mill operating rate is the ratio, which the actual time of operating is to the total hours' calendar during the work. The ration is usually calculated once a month. The mill operating rate of the whole plant is calculated according to the average value of all mills, and the actual operation also includes the idle time.
