Oct 20, 2008 . In terms of milling efficiency defined as the amount of material milled to 150μm per minute, it was found that there was no optimum load size; doubling the sample size effectively doubled the milling time. However, the most critical factor affecting the milling process, was the weight and nature of the grinding.

mill discharge density (before dilution) obtained during the sampling. The ball charge, and hence the volume of the voids between the balls in the mill, is known and we are then able to calculate the factor 'volume pulp/volume voids between the balls'. Repeatability. The repeatability of the pilot plant was investigated in the.
