     · If a mill has available power, conversion of the discharge arrangement from overflow to grate can be beneficial in allowing increased throughput or a finer product size. Conversely, if the mill does not have available power then it is still possible to install a grate discharge and to draw the same power by using a lower ball charge.

     · For an overflow ball mill, the increased slurry pool volume resulting from the increased mill feed rate will not lead to an increase in ball mill power draw; rather more often the opposite. This is attributed to the fact that the slurry pool on the opposite side of the rising ball media would counter the torque required to rotate the mill shell and lift the ball media, leading to a decreased ...
