Calculate and Select Ball Mill Ball Size for …
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 ...
CALCULATION OF THE POWER DRAW OF DRY …
in a specified laboratory mill. Then, using empirical equations developed by Bond, and later with minor revisions by Rowland, the mill size is determined (Rowland, 1985; Napier-Munn et. al., 1996; Man, 2000). Once, the size and ball load is determined, the power draw for a given mill is calculated using Equation 1. * Hacettepe University, Department of Mining Engineering, Ankara, Turkey ...

THE OPTIMAL BALL DIAMETER IN A MILL
The ball size in a mill has a significant influence on the mill throughput, power consumption and ground material size (Austin et al., 1976; Fuerstenau et al., 1999; Kotake et. al., 2004). The basic condition, which must be met while grinding the material in a mill is that the ball, while breaking the material grain, causes in it stress which is higher than the stone hardness (Bond, 1962 ...
