scale up of power consumption in agitated ball mills

Scale‐up of power consumption in agitated ball mills ...

Previous investigations have shown that the specific energy input is the overall parameter of influence on product size during communition in agitated ball mills, from laboratory up to industrial scale. The specific energy input is the introduced energy related to the amount of comminuted material. This parameter can be used for mill scale‐up.

Comminution and transport behaviour in agitated ball

1992-1-1 · Experimental investigations have been carried out with different size agitated ball mills (4-200 l) and different materials (limestone, hard coal, microorganisms). The specific energy input has been found to be the most important parameter influencing the comminution result. A method for scale-up and prediction of power consumption is described.

Analysis of Power Draw in Ball Mills by the Discrete ...

Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated
