2. from the ball mill discharge size distribution calculate the %+75 μ as: 100 – 26.5% = 73.5% +75 μ. 3. calculate the cse as the average: (80.7 + 73.5) 2 = 77.1% + 75 μ. in this example the ball mill circuit classification system efficiency is 77.1 per cent at 75 μs. this means.
A system combines this data to estimate the impact of the steel balls on the liner and infer conditions inside the mill. based on this information, mill operators can adjust operational parameters – such as mineral feed and rotational speed – to optimise mill performance, and prevent the liner’s.
Abstract. the ball mill in closed circuit with hydrocyclones is an industry standard, and well known methodologies exist for equipment sizing, selection and design; however, the potential to improve the capacity of ball mill circuits by replacing cyclones with screens has been recognised for many years and recently has been successfully realised, thanks to developments in fine screening.
