Ball mill - Wikipedia. A planetary ball mill consists of at least one grinding jar which is arranged eccentrically on a so-called sun wheel. The direction of movement of the sun wheel is opposite to that of the grinding jars (ratio: 1:-2 or 1:-1). The grinding balls in the grinding jars are subjected to superimposed rotational movements, the so ...

To accelerate the math or calculation you can use the shortened formula: D m <= Km * d^0.5where Km =6 (log dk) is taken from Figure 5 according to the fineness of the finished product dk. These formulas are applicable to the case of feeding a mill with only single-sized balls and not a mixture without consideration for ball wear.
