Mills with the rod mill and ball mill laboratory work indices.Note, in figure.1, that the rod mill product slope is less than 0.5 due to an extra amount of nes present being ner than 650 m.These nes proceed to the ball mill improving the ball mill ef ciency.Also, the plotted rod mill p80 value, as shown in figure 1, is 2900.
Effect of circulating load and classification efficiency on hpgr and ball mill capacity.
The mill was attached to a drive shaft, supported on bearings, and driven by a freely-suspended gearbox and motor.The torque on the drive assembly was measured on-line and the average value was used to calculate power.The surging of the mill load caused the torque to oscillate.Mill charge fillings of 30 and 40 were tested.
