Mar 27, 2020018332The charge volume of a ball or rod mill is expressed as the percentage of the volume within the liners filled with balls or rods. When the mill is stationary, the charge volume can be quickly obtained by measuring the diameter inside the liners and the distance from the top of the mill inside the liners to the top of the charge.
quoted priceCalculate ball mill grinding capacity.A total apparent volumetric charge filling including balls and excess slurry on top of the ball charge, plus the interstitial voids in between the balls expressed as a percentage of the net internal mill .
Commercial ball sizes 10 150 mm Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney 1937 defined the ball size as a function of the top size of the feed, , d226V K226F
Investigation is to determine if liberation can be changed by mill operating parameters. It is hoped that this work can be used as a precursor to the development of a model that can predict liberation given the various ranges of operating parameters. Mill speed, mill charge, ball size, and wet grinding are the parameters which have been selected

But efficiency of ball milling depends upon many factors like Ball dia, PCA used, Rotational speed, type of charge. For a ductile charge it should be better with 151.
Jan 07, 20150183323. Friction between the lining and the grinding media. 4. Internal friction mill charge. Figure Grinding media 4.4.1 Grinding Ball Charge in Mills According to Levenson, the optimum grinding ball charge should be r - 0.16D The degree of ball charge varies with in the limit of 25 and 45. A ball charge below 25 causes sliding of the balls.
Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge. GET PRICE
While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. PDF A comparison of wear rates of ball mill grinding media. A comparison of wear rates of ball mill
