Ball Mills - an overview | ScienceDirect Topics

Generally, filling the mill by balls must not exceed 30–35% of its volume. Productivity of ball mills depends on drum diameter and the relation of drum diameter and length. Optimum ratio between length L and diameter D, L:D is, usually, accepted in the range 1.56–1.64. The mill productivity also depends on many other factors: physical-chemical properties of feed material, filling of the

Calculate and Select Ball Mill Ball Size for

02.08.2013· In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

22.10.2020· The mill speed is one of the vital parameters in ball mills, which is normally specified as a fraction of critical speed. It determines whether the load behavior is predo-minantly the cascading regime, the cataracting regime or the centrifuging regime. In general, the industrial ball mills rotational speed operates at 70%~80% of critical
