The results of the total intrusion volume, average pore diameter and specific surface area of fly ash samples, shown in Fig. 2, presented the great changes of those parameters with the ball-mill time.The total intrusion volume and average pore diameter decreased sharply as the milling time was increased and exhibited small peak when the ball mill time …

The average zinc recovery rate for an MZR-2000 is approximately 60 percent. By contrast, the grinding and screening of the ball-mill process delivers approximately 35 percent recovery. A lower recovery rate means more material is sent back through the roaster. If Pyrotek's zinc-recovery system can increase a casthouse's plant capacity by ...

The proper operating speeds of ball-mills vary inversely as the square-root of the diameters. The proper operating speed of a ball-mill increases as the size of the ball load increases. Due to interference between the balls, the volume of the charge should not be over 60 per cent, of the volume of the mill.
