size ball mill was used with ball media of sizes 10 mm, 20 mm and 30 mm respectively. Quartz was the material used to perform the experiment and was arranged into 3 mono-sizes namely -8 mm +5.6 mm, -4 mm +2.8 mm and-2 mm +1.4 mm for the experiment. A mill run having a mixture of the 3 ball diameter sizes was also conducted. It was
The feeding moisture of ball mill is required, generally less than 6%. If it is above the standard, the material will adhere to ball mill during the grinding, thus resulting in lower productive efficiency of ball mill, and also blocking the air circulation channel and discharge opening of analysis ball mill etc.

Thus, the specific gravity of the slurry and the impact of the viscosity giant on the ball mills are great. Practice proves that the specific gravity of the slurry in the ball mill is controlled in the medium and high aluminum ball 1.83 ~ 1.90, the natural pebbles 1.75 ~ 1.83, the viscosity is 30 ~ 60 seconds, and its ball mill is high.
Rod mill grinding efficiencies have been shown to increase in the range of 5 to 15% with more dilute discharge slurry (i.e., increased feed water) at least down to the range of 45 to 50% solids by volume. The higher the discharge % solids in the plant rod mill, the better the candidate for feed water addition rate test work.
