On the class of work for which it is especially suitable the power consumption of a rod mill is about three-quarters that of a ball mill with the production of less undersize. The rod and liner consumption is also about 75% of that of a ball mill, and rods cost less than balls because they are more easily manufactured.

The diameter of a ball mill has a great influence on the power consumption of the mill and thus on the possible production output. This is because the ratio of the diameter to the grinding path length determines the residence time of the material in the mill and thus the theoretically achievable fineness of the material at the discharge.

Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill circulating loads of >1000 per cent.
