The pilot mill is also equipped with a sensor measuring the 'ball and pulp toe and shoulder angles' (see Figure 3). These data are then used to calculate the total pulp and ball charge angle (see Graph 5). Graph 5 clearly illustrates how the ball charge stays quite compact till about 73% solids as the total media angle does not change.

Efficiency and grinding media filling level

This presentation was given at a time when a 1000 horsepower ball mill was considered a "giant" and the goal was to get as much energy from the lowest mill volume requirement. For this reason, funded research for possible efficiency gains from low ball charge filling levels was not allowed by the corporation they worked for.

Exploring ball size distribution in coal grinding mills

J is the ball filling fraction. ρ charge is the overall charge density calculated as follows: ρ charge = total coal mass + ball mass / J ∗ Mill volume. α is the angle of repose, which is estimated to be about 35. Mill capacity increases linearly with increasing ball load for both ball sizes within the considered range.
