Rod milling in the Magotteaux Mill Grinding

After some trial and error it was decided to go for a rod charge of approximately 45kg. This equates to a charge of around 40% by volume, but this of course includes a certain void between rods. For a rod charge with a single diameter it is relatively well-documented what the packing and hence void

AG Autogenous & SAG Semi-Autogenous Mill

2021-5-3  Experience to date has indicated that the ball charges used in semi-autogenous grinding have generally been most effective in the range of 6% to 10% of the mill volume including the void spaces between the balls, i.e. ball charge volume based upon 290 lbs. per cubic foot.

Optimizing cement grinding with chemical additives

2021-3-11  Influence on mill retention and void filling. There is an optimum powder filling level in the mill, relative to the media volume to ensure maximum grinding efficiency. This occurs when material fills approximately 85% of the media voids. However, mill operation at high circulating loads often results in a void filling somewhat above this amount.

Several factors influence the efficiency of ball mill

Balls of very hard material, however, may lead to lower grinding efficiencies due to slippage. The charge of balls to the mill is about 40% to 50% of the internal volume, with approximately 40% of this being void space. The energy input to a ball mill increases with the ball charge, and 40% to 50% is rarely exceeded.
