Closed circuit ball mill

1 Introduction Over the years ball mill circuits closed with cyclones have become an industry standard and since the early days it has been recognised that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit grinding (i e its capacity to produce the desired final product) Get price

Mill (grinding)

F 80 is the mill circuit feed size in micrometers Rod mill A rotating drum causes friction and attrition between steel rods and ore particles [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill which makes rods of iron or other metal Rod mills are less common than ball mills for grinding minerals Get price

Effect of circulating load and classification efficiency

Both ball mills and HPGRs are typically used in closed circuit with classifiers There is a general consensus within the industry that classification efficiency and circulating load both have a major effect on the efficiency of closed circuit ball mills Get price
