Grinding circuit design principles Matallurgy SRK

Grinding circuit design principles. For semiautogenous grinding (SAG) mills, there are two basic forms of testing single particle breakage and tumbling tests designed to recreate the actual mill environment. For high pressure grinding rolls and regrind mill sizing, a specific test designed for that piece of equipment is best.

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 (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
