Towards a Better Understanding of Stirred Milling ...
mills are illustrated in figure 1. Almost all of these stirred mills can be described as a concentric impellor of some geometry inside a circular or near circular chamber. The only exceptions noted are the MaxxMill series of mills (see fig. 1d) where the impellor is offset from the center of the chamber in order to provide

CALCULATION OF THE POWER DRAW OF DRY .
Calculation of the power draw of dry multicompartment ball mills 225 The mill load that is the volume of charge in the mill is the principal determinant of power draw. Estimation of the ball load that is mixed with the cement charge is difficult and can be highly erroneous. So direct measurement must be taken for calculation of mill load.

DETERMINATION OF POWER CONSUMPTION IN MILLING
With the instantaneous milling cutter position calculated at point D(t), the transport of the moments is performed from the milling cutter center (point S(t)) to the tooth tip (point D(t)). M / D =M / s +DO∧R (13) The power calculated based on the formulae given by the different tool manufacturers represents the average power used during milling.
