The void volume between the grinding media, with the mill half charged, represents approximately 20% of the total volume of the mill.Fastest grinding occurs where there is just sufficient material in a batch to fill all voids and slightly cover the grinding media. The material should never be allowed to drop below the surface of the grinding media, because when this happens, excessive wear occurs to the mill and grinding media and contaminates the material itself. The largest size batches should not exceed 60% of total mill volume.
We should establish the batch size consistent with the allowable running time. It is recommended to do a little experimentation with the batch size to try to develop a system that will work out best under particular grinding conditions. The one principal rule to remember is that the grinding media must be covered with material.Viscosity – The most important element in wet grinding is the viscosity of the batch. Low viscosity materials permit the grinding media to move with excessive speed and this may cause abnormal wear, contamination and heat build-up. If the low viscosities cannot be avoided then it is imperative that small grinding media be used.With high viscosities free movement of the grinding media is impeded. This can cause a carrying over and “throw” of the media resulting in inefficiencies and contamination.
