Jan 01 2016 The fraction of void space between the balls in the ball charge filled by rock when the mill is at rest is given by the ratio of J R J B φ U. Normally the bulk rock occupies 20–25 of the mill volume and the balls in a ball mill occupy the remaining charge volume during dry grinding.

Mar 27 2020 The charge volume of a ball or rod mill is expressed as the percentage of the volume within the liners filled with balls or rods. When the mill is stationary the charge volume can be quickly obtained by measuring the diameter inside the liners and the distance from the top of the mill inside the liners to the top of the charge.

Tumbling ball mills or ball mills are most widely used in both wet and dry systems in batch and continuous operations and on a small and large scale. Grinding elements in ball mills travel at different velocities. Therefore collision force direction and kinetic energy between two or more elements vary greatly within the ball charge.

We can calculate the steel charge volume of a ball or rod mill and express it as the of the volume within the liners that is filled with grinding media. While the mill is stopped the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The loading or change volume can then be read off the graph below or
