May 6, 2004 . In this paper, a new approach for the calculation of the power draw of cement grinding ball mills is proposed. For this purpose, cement grinding circuit data including the operational and design parameters were collected from 14 industrial ball mills, ranging in diameters from 3.2 to 4.8 m. The ball loads.

We use a simple model for grate discharge that allows prediction of the time varying axial distribution of different particle sizes within a discharging ball mill. The distributions of sub-grate size 'fines' is shown to satisfy a one-dimensional diffusion equation with the diffusion coefficient decreasing with grate size. A pulse test.

The calculated relative error was 0.25%. In the ball mill, the estimated error for the radius was calculated as 7.3 mm. Considering that the liners were worn and that it was not possible to ensure that the laser was pointed precisely at the bottom region of the liner waves, this error can be considered very acceptable and.
