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 are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (, via a hand crank), working animal (, horse mill), wind or water ().
Crushers have more efficient transfer of applied power to the breakage of rock than grinding mills. Typically a crushing flowsheet for a mineral processing plant will have from onetothree stages of crushing. There are some cases where the process requires a fine dry product and a quaternary stage of crushing will also be included. Primary ...
