Example - To calculate grinding media charge for a 180 cm dia x 180 cm long batch type ball mill with Duralox 50 mm thick bricks. Formula to be used is M = 0.000929 x D2 x L D = 180 - 10 = 170 cms L = 180 - 10 = 170 cms Therefore M = 0.000929 x (170)2 x 170 Grinding media quantity = 4564 kgs. Silica ore was used as the test material. The experimental parameters that were kept constant in this investigation was the grinding media filling, powder filling and the mill rotational speed. The data obtained from these batch tests was then analyzed using a …
