Effect of lifters and mill speed on particle behaviour

May 01, 2017· The power of a ball mill is obtained by multiplying the corresponding torque with the mill speed. Thus, the torque curves and power curves are similar. Fig. 20 shows 78 groups of DEM simulation results for the effect of rotation rate, lifter height, and lifter number on the power draw of the ball mill. Each curve represents the variation of the

Optimization of mill performance by using

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
