mills whose grinding medium consists of steel balls are called ball mills. they are used in mesh and finer grinding. generally, they are used in the final stage of milling. In these mills, which produce a thinner product compared to rod mills, the ratio of neck to diameter varies between and 1,5.ball mill. inside a ball mill, the balls move round in a circle as the mill turns, crushing the ore into a powder. this process of reducing the size of the rocks requires a lot of energy. just image how hard it is to break a rock. how much more energy do you think is needed to crush a rock until it is like sand?improvements IN sag mill throughput from finer feed size AT the newmont ahafo operation adrian danc, sonny mwans, walter valery george amono and bryon bisiau RK consulting inc floor, 1066 west china ton per day rice plant rice mill machine, find details about china rice machinery, combined rice mill from ton per day rice plant rice mill machine
