The grinding jars are arranged eccentrically on the sun wheel of the planetary ball mill. The direction of movement of the sun wheel is opposite to that of the grinding jars in the ratio 1:-2 (or 1:-2.5 or 1:-3). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so-called Coriolis forces.

This study aims to develop a new approach toward estimating the Bond ball mill work index (BBWI) by applying a series of kinetic grinding tests with Bond standard mill.
When the grain size of the raw material reaches the nanometer scale, it becomes more reactive and reacts with the gas in the ball mill tank, causing contamination of the powder product. The atmosphere in the ball mill tank may remain vacuum or semi-vacuum after the products of the ball mill react with the gas in the ball mill tank.
