The maximum power draw in ball mill is when ball bed is 35-40 % by volume in whole empty mill volume. Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be ...
Calculating Power Draw when sizing Ball Mills Grinding I believe that as circulating load in a ball mill increases beyond a critical point the mill power draw begins to fall so there is an adverse effect on grinding efficiency (apart from the obvious physical problems it causes like high scats rates, balls discharged from mill, sumps overflowing, cyclones clogging up etc.).
GROSS POWER CALCULATOR General This model uses the equations from Morrell's 1993 PhD thesis: "The Prediction of Power Draw in Wet Tumbling Mills". The model is also described in detail in the book "Mineral Comminution Circuits Their Operation and Optimisation" which is available from the Julius Kruttschnitt Mineral Research Centre.

Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between

Calculation of the power draw of dry multi-compartment 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.
mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge).
