A motor with around 1400 Horse Power is calculated needed for the designed task. Now we much select a Ball Mill that will draw this power. The ball mill motor power requirement calculated above as1400 HPis the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power …

In a pebble mill the pebble consumption ranges from3—15% and the charge has to be controlled automatically to maintain uniform power consumption. The volumetric density of a rod and a ball charge is around 4.9 ton/m³ (310 lb/cu.ft) corresponding to 37 % void space.
