Improving Energy Efficiency in Barrick Grinding Circuits eex.gov.au Grinding, semi-autogenous grinding, SAG, ball mill, energy, efficiency, greenhouse gas, the lifters and also reduced the modeled impact of the ball charge on the . also provides the opportunity to better trim the SAG mill speed.
2013-9-1Batch grinding tests were carried out using a 25.820.8 cm lengthdiameter ball mill equipped with 4 lifters. The LD ratio in both laboratory ball mill and the plant ball mill was similar. The maximum ball size calculated from Bond formula for plant ball mill Eq. was 30 mm. 5 d B mm 25.4 F 80 k 0.5 s. g. W i 100 C s 3.281 D 0.33.
2007-4-3The Bond ball mill test is designed to predict power in wet ball mill grinding circuit operating at a 250 circulating load. However, moving away from this condition reduces the accuracy of the test. Further, the Bond ball mill test does not predict the behavior of large rocks in a grinding circuit where the mode of breakage is impact dominated.
2016-4-22How to optimize the grinding process in the situation of wet grinding Usually,the total charges of alumina ball in one ball mill should be not less than 55 of the total ball mill capacity.
