reason for effect of mill speed on grinding pdf
Welcome to CDC stacks | Effects of turbomilling parameters ...
The effects of mill rotational speed and volume percent solids on the leaching time and energy required for copper extraction from chalcopyrite were evaluated. The results of this laboratory study have shown that the simultaneous grindingleaching of chalcopyrite concentrate using the turbomill is technically feasible with essentially 100pct extraction of copper being possible at 90 deg C.

Producing a finer grind with a largerotor, highspeed ...
Grinding efficiency Impact is the more efficient of the two grinding forces. Thus, increasing the hammertip speed, which increases the amount of impact between hammers and particles, improves hammermill grinding efficiency. When two units run at the same motor speed, the unit with the larger rotor diameter has a faster hammertip speed.
