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 working animal wind or waterfor the mining industry, our semi-autogenous grinding mill uses a minimal ball charge in the range of percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. autogenous grinding mills involve no grinding media as the ore itself acts as the grinding media.In a mining plant or processing mill, they have a big grinding circuit for crushing raw material, these are usually ball or sag mills. inside these sagball mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being
