The grinding jar is 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. The grinding balls in the grinding jars are subjected to superimposed rotational movements, the socalled Coriolis forces.
balls which exist in mill, 𝐴𝑏: each ball abrasion (g), 𝐴t: total ball abrasion in the mill (g), 𝑣b: each ball volume (m3), 𝑓b: supposed ball filling percentage, A r: ball abrasion rate in the mill. If above calculation were done again for 𝑓b = 2%, total ball abrasion will get, finally.
