### Calculating Power Draw when sizing Ball Mills - Grinding ...

If you size a ball mill based on Nordberg; you use the hardness to derive the needed power to reduce to a target size at a particular throughput. From that "power draw" you calculate a shell size from 4 parameters: diameter, effective length, wet or dry? %loaded and % of critical speed.

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.

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.
