Mill (grinding)

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 processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Potash Corporation of Saskatchewan Potash Mine

Run-of-mine ore is dry-crushed and screened in a two-stage circuit before being slurried in a saline solution together with the fines prior to pumping to a sizing screen distributor. Mill feed is then de-slimed in a circuit of three scrubbing tanks for stationary screening, hydroseparating and thickening.
