A mill is a device that breaks solid materials into smaller pieces by grindingcrushingor 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 vertical pre-grinding mill makes use of pressing force and shearing force for material grinding. It offers better grinding results than roller mills. When used for cement raw material and cement clinker pre-grindingthe pre-grinding machine can increase production capacity by 100% and 50%respectivelywhile reducing electricity
