the mill power applied to coarse material, i.e., larger than the reference size, therefore: CPR (t/h) = mill power applied to coarse material (kW) × mill grinding rate of coarse material (t/kWh) The circuit classification system efficiency (CSE) is the percentage of the mill solid material content that is coarser than the reference size.

difficultto process, transport, install and maintain the gearless ball mill because of its vast volume, and the coils cannot be decoupled freely. Therefore, this work proposes a module combined permanent magnet motor with wrapped type for mine ball mill (MBMWT‐MCPMM). Based on the principle of removing coils, the stator is modular-ized.

Ball Mill Motor Power Draw Sizing and Design Formula. The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

Ball Mill Working Principle. To be chosen according to the grinding material, material is composed of a ball mill feed end of the hollow shaft is arranged in the tube body, when the ball mill cylinder rotation time, grinding body due to inertia and centrifugal force, the effects of friction, making it attached to the cylinder liner on the cylinder body away, when taken to the height of a ...

The pilot mill is also equipped with a sensor measuring the 'ball and pulp toe and shoulder angles' (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite compact till about 73% solids as the total media angle does not change.
