A discussion on the measurement of grinding media wear ...

01-07-2016 · The volumetric theory of ball wear states that the wear rate of a ball is proportional to its mass and, therefore, it is also proportional to the cube of its diameter (that is, to its volume). The origin of this theory considers that most comminution events result from impact mechanisms–which do not occur in laboratory mills, given their reduced diameter as

Calculate and Select Ball Mill Ball Size for Optimum Grinding

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
