Very large tonnages can be ground with these ball mills because they are very effective material handling devices. Ball mills are rated by power rather than capacity. Today, the largest ball mill in operation is 8.53 m diameter and 13.41 m long with a corresponding motor power of 22 MW (Toromocho, private communications).
The level variation of electrolyte is pretty slow, which does not enable resistance to vary quickly enough for some specific applications (control of the slip for the ball mills for example). Why using a starter for slip ring motors. In order to start a slip ring motor, the accelerating torque has to be sufficiently higher than the resisting

Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009. Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ‘chunk size’, product size as P80 and maximum and finally the type of circuit open/closed
grinding process [15, 18, 22, 28]. A comparison between ball mils and cylpebs is made in [ 42]. The speed of rotation of the mill determines three basic types of operation modes: slow rotation (cascading), fast rotation (cataracting) and very fast rotation (centrifugation). Each type is characterized by a specific trajectory of motion of the
