Wear of grinding media. One of the major problems regarding the use of ball mills is to balance the size distribution of grinding media into the mill, which is determined by the speed of consumption and rate of replacement [3], as the wear of the grinding balls requires their substitution at intervals.

Critical Speed and a Grinding Ball. For the ball mill to work properly, it must reach critical speed. This is the speed at which the grinding balls start to spin along the ball mills' interior walls. If the ball mill does not reach critical speed, the grinding balls will stay at the bottom. They won't be able to grind the material properly.

For Ball milling and most other applications, the ratio between the speed of the sun wheel and the speed of the grinding jar is 1: 2. This means that during one rotation of the sun wheel, the grinding jar rotates twice in the opposite direction. This speed ratio is very common for Planetary Ball Mills in general.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

According to Cleary (2001), grinding in ball mills is still far from being effective due to high consumption of electrical energy and steel (grinding media). Currently, the cost of steel balls amounts to 45% of the total cost of grinding materials in ball mills (Lameck, 2005). The remaining costs include energy consumption and ball mill lining.

A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell. Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in twostage grinding circuits.
