Mill (grinding)
A mill is a device, often a structure, machine or kitchen appliance, 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 animalsAlthough the introduction of autogenous and semiautogenous milling for comminution circuits has lead to a number of economic advantages, from a process viewpoint at least one downside has been theirFeed size and blasting ResearchGate
