The larger the diameter is, the slower the rotation will be. Ball Mills are generally used to grind material and finer, down to the particle size of 20 75 microns. To achieve reasonable efficiency, the ball mills are to be operated in a closed system, with oversize particles continuously being re circulated back to the mill and to be reduced.Mill Power Draw Models. The mill power draw models are used to predict how much power will be consumed by a particular type of mill, mill geometry and set of mill operating conditions. This power is transferred to the ore and used to predict the throughput when combined with the specific energy consumption models.
