  • 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 processesThere are many different types of mills and many types of materials processed in them Historically mills were powered by hand or by animals (eg, via a hand crank), working animal (eg, horse mill), wind or water ()The size of bearing balls has to be perfect, sometimes within millionths of an inch, so a few more operations are needed after heattreating The balls next go through a grinding operation The same kind of machine is used, but this time the coolant contains an abrasiveHow do they get the balls in ball bearings so perfectly A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sinteringIt works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shellBall mill Wikipedia
