An overfilling indicator for wet overflow ball mills ...

The lack of constraints in ball mill capacity in the published ball mill models may result in unrealistic predictions of mill throughput. This paper presents an overfilling indicator for wet overflow discharge ball mills. The overfilling indicator is based on the slurry residence time in a given mill and given operational conditions.

ball mills in producing the final product (particles finer than 74 µm) was 55.38% and 44.62% respectively. That is the SAG mill produces about 10.76% more than the ball mill in the final product. The average consumed energy at SAG and ball mills to produce one ton of final product was 23.16 kWh/t and 36.05 kWh/t respectively.

mill capacity for wet grinding 2. mill capacity for dry grinding. Solution. Mill Capacity for Wet Grinding. Step 1. Since the mill size is less than 3.8 m Equation is applicable: The combined correction factor (C F) is taken as = 1. Step 2. The critical speed is given by Equation as ν C = 42.3 3.0 − 0.101 = 24.8 rpm therefore ϕ C = 21/24.8 = 0.85
