Charge behaviour and power consumption in ball mills

Aug 01, 2001 The specific power consumption for these two ball shapes is shown in Fig. 16. For N≤75% 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.

Is the power consumption of planetary ball mill large

Planetary ball mill is a kind of ball mill that many consumers will choose. Is the power consumption of this kind of ball mill large? In fact, there are many kinds of planetary ball mills in the ball mill market. the working efficiency and power consumption of each kind of ball mill are different.

Charge behaviour and power consumption in ball mills

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.
