As you increase the volume of the through put, the time that the ore has to react to the grinding media is lessened. As you add ore to the mill you are also adding WATER and changing density which affects the slurry rheology and workings of the grinding action inside that mill. This water is one- of the main controls that you have over your grind.

Effect of Balls Hardness on Rate of Grinding Tests by Coghill and Devaney show that the hardness of the balls has some effect upon the rate of grinding in mill. These results are plotted in Fig. 6.8a and it is seen that, both for dolomite and chert, there is an increase in the rate of grinding

Density, if you recall is the ratio of ore to water and is measured as a percent of solids in the water. It will control the grind in two ways. It affects retention time and helps distribute the ore through-the mill so each piece of rock will come in contact with the surface of the rods. To maintain a proper balance between these two is critical.

The cyclone cut point matches the grinding capability of the mill. As the circulating load increases, the cyclone feed density increases and associated product size increases. If the circulating load decreases, the cyclone feed density decreases and a finer product size is produced.

The mill capacity can be estimated by dividing 90% of the gross mill power by the net grinding power per tonne from the test mill. Several workers have attempted to determine the power draw for autogenous and semi-autogenous mills,,,.
