Get PriceOptimum choice of the makeup ball sizes for maximum. For a single size of makeup ball, the mass fractions in the mill within the size ranges are calculated from: (11) m k = d k u 4 Δ d k l 4 Δ d max 4 Δ d min 4 Δ where d k u and d k l represent the upper and lower boundaries of the ball size interval k, dmax is the largest ball size in the mill, and dmin is the smallest ball size in the ...
Aug 30, 2019 1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...
base are up to 40ft in diameter and ball mills are up to 26ft in diameter. The measured gross power draws from these mills are plotted against the model predictions in Figure 1. As indicated by this data base the accuracy of the model (1 standard deviation) is 4.6%. How to Use the Model . Inputs to the model are made in three windows, viz: Mill ...

Mill power Usually, plant operators use mill power readings as an indicator of ball filling degree and, often, try to keep it at the maximum level. It is well known that the mill absorbed power depends on operating parameters other than ball level, such as pulp density and liner configuration. Figure 2 shows that there is no linear relation between
