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 ()Dec 26, 2015· Since there are not that many small SAG mill operations of under 2000 TPD, and most sub2000 TPD mills are built with rod mills and/or ball mills only; the upstream crusher plant needs to have sufficient crushing power to provide a P80 to grinding of typically <15″ (40 mm) and often as finely crushed as <3/8″ (9 mm)Crushing in Mineral Processing
