  • 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 (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

    The power drawn by the SMD motor is required to establish the grinding rate. As the grinding media wears fine enough to exit through the mill screens, the total media charge will diminish, and the power draw will decrease. Media should be added either manually or automatically to maintain as consistent a power draw as possible. SMD is normally
