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 ().

Types of Milling Operation - AS PRECISION
Side Milling. The side milling is the production of a flat vertical surface on the side of a work piece by using a side-milling cutter. The depth of cut is adjusted by rotating the vertical feed screw of the table. Straddle Milling. When two or more parallel vertical surfaces are machined at a single cut, the operation is called straddle milling.
Ball Mills - Mineral Processing & Metallurgy
Ball Mill Grinding Circuit. Even though many ores require fine grinding for maximum recovery, most ores liberate a large percentage of the minerals during the first pass through the grinding unit. Thus, if the free minerals can be immediately removed from the ball mill classifier circuit, there is little chance for overgrinding.
