In grinding selecting calculate the correct or optimum ball size that allows for the best and optimumideal 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 andor mill liner wear and
Investigating the controllable factors influencing the weight loss of ball mills are the most common and versatile type of grinding mills mild steel or stainless steel balls are generally used as grinding media in ball mills for of ball mill rotation speed of mill charge weight of balls and grinding time before and after each grinding experiment were weighted to calculate
Material in the mill including the media which may be steel balls in a ball mill or large lumps of ore in an autogenous mill or a mixture in a semiautogenous mill as well as the slurry that makes up the operating charge let jt be the fraction of the mill volume that is occupied by the total charge jb the fraction of the mill
Mill absorbed power and ball filling degree as indicated on the graph a small variation in power could be the result of a significant variation of balls filling degree as the ball wear rate depends directly on the surface of the media charge a small variation in power will lead to an important increase of wear rate the risk of underloading
