### Grinding Media Wear Rate Calculation in Ball Mill

In any mill, the rate at which the surface of any ball decreases is proportional to its surface. Since the rate at which a ball loses weight varies as the work done upon it in the mill, it follows that the work done in wearing (or crushing) the ball varies as the weight of the ball…

### Calculate and Select Ball Mill Ball Size for Optimum Grinding

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.

The mill used in this experiment is made of alumina with an inside diameter of 144 mm and an inner volume of 2100 cm 3, and the grinding ball is also made of alumina.Five ball diameters ranging between 3 and 30 mm were used, and feed size was varied in the order of 10 −3 to 10 −1 as a ratio of ball diameter. Feed sizes and ball diameters used are shown in Table 2, Table 3, Table 4.

### Estimation of shear rates inside a ball mill - ScienceDirect

Grinding slurries are known to be non-Newtonian. For such suspensions, slurry viscosity is not a constant, but is a function of shear rate. This study was aimed at the derivation of an estimate of a typical shear rate range inside a ball mill, in order to determine appropriate values of apparent viscosity for studies of the effects of rheology on grinding.
