Analysis of power draw in ball mills by the discrete ...

Mar 01, 2020· It was reported that for a ball mill with 5 m diameter and 7 m length, the power draw can be between 2.5 and 3.5 MW, only 1–5% of this energy uses for the size reduction as an actual duty of milling . Therefore, estimation of power-draw can be considered as an indicator for a mill performance,, .

Ball Mill Motor Power Draw Sizing and Design Formula

This ball mill and rod mill power draw model is based on a torque model and empirical measurements made by the Equipment Company for use by its sales representatives to size grinding mills. Slight differences in the equations used allow rod mills, dry ball mills and wet overflow and grate ball mills to be sized.

Power Draw Ball Mill

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

Benchmarking: Ball Mill Power Draw Models - SAGMILLING

Apr 01, 1999· But as the mill speed approaches the critical value more number of balls start to stick on the mill shell, the effective ball mass reduces and thus, the mill tends to draw less power. In this context, one should realize that the peak of the curve would depend upon friction between mill shell and …

Power-draw prediction by random forest based on operating ...

predicted. Slurry pooling causes the power draw in AG and SAG mills to be lower than a mill without a slurry pool. This phenomenon results in overflow mills usually drawing less power than grate discharge mills that are operating without a slurry pool. This is because by definition overflow mills operate all of the time with a slurry pool.
