  of overflowdischarge mills but not to the same extent in gratedischarge mills. This pool is situated more or less symmetrically with respect to the axis of the mill and therefore does not draw significant power. Austin recommends K = for overflow semiautogenous mills. A value of K = makes Austins formula agree with Morrells data

  Converting a ball mill from overflow to grate discharge

  This is different to an overflow mill which holds the slurry and balls inside until the slurry builds up to a level at which it is possible to overflow out of the discharge trunnion. Mill power draw The installed motor power for a grinding mill is a key indicator, along with the physical dimensions of the mill itself, of the capacity of the mill to process tonnes of ore.
