Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 Planetary ball mills. 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 according to a fixed ratio. The grinding balls in

Ball Mill Drives Mineral Processing & Metallurgy

22/10/2016 These assume no greater than a 10% voltage drop at the motor terminals. V-BELT Ball Mill DRIVE. V-belt or poly-V drives are generally used on grinding mills consuming 350 HP or less. Where power exceeds this, drives become so large and motors become special, resulting in an uneconomical application. Generally the driven mill sheave is of split hub construction to facilitate field
