Throughput was hence estimated to be 1636 dry tonnes/hr. Power draw data were confirmed as being measured at motor input. The Morrell Method for grinding mills is based on predicting the specific energy at the pinion shaft. To adjust the power draw measured at the motor input to power at the pinion a 6.5% correction was made.

It's not uncommon for a large mine to have independent planners looking after blasting, primary crusher throughput, secondary and ball mill grinding as well as the concentration plant. A single-minded focus by any of these groups to maximize throughput may come at the expense of other units, and ultimately at the expense of overall throughput.

key factors affecting mill throughput and grinding efficiency: mill speed, ball loading, and liner lifter face angle (angle between the lifter face in contact with a grinding ball and the lifter base). Its central hypothesis is that face angle drives a ball mill's grinding efficiency and throughput independently of the type of liner used.

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product discharges ...
