Effect of Water & Density on Grinding Mill

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.
