Aug 01, 2001 The specific power consumption for these two ball shapes is shown in Fig. 16. For N75 there is no change in the mill power draw. This occurs because the center of mass of the charge is little changed by the particle shape at these speeds. At intermediate speeds, the power draw for the non-circular balls falls off rapidly.
Aug 30, 2019 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material grain size, hardness, density, temperature and humidity, the degree of ...
The combination of these effects means that the speed for which peak power consumption occurs is predominantly determined by the shear strength of the charge material and the fill level. This demonstrates the sensitivity of mill behaviour to the charge characteristics and the critical importance of various assumptions used in DEM modelling.

the mill power and the efciency of the mill operation Van Nierop and Moys, 2001. If a SAG mill has been designed with a conventional power or specic energy model which do not con-sider the projected feed size distribution it is likely that this mill will reach the expected power consumption
Oct 18, 2016 Although mills have great energy consumption, only a small part of this energy is converted into actual particle fragmentation. As an example, Cleary 2000 points out that the power consumption for a 5 7 m ball mill can reach 3.5 MW and only 1 to 5 of this power is directed to size reduction So why are tumbling mills so very inefficient
