2015-10-15 Calculate Ball Mill Grinding Capacity. The sizing of ball mills and ball milling circuits from laboratory grinding tests is largely a question of applying empirical equations or factors based on accumulated experience. Different manufacturers use different methods, and it is difficult to check the validity of the sizing estimates when estimates ...

MoreGenerally, filling the mill by balls must not exceed 30%–35% of its volume. The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length. The optimum ratio between length L and diameter D, L: D, is usually accepted in the range 1.56–1.64.

More2021-2-19 Optimization results confirmed that the balls to powder weight ratio were the most influential process parameter. The optimum process parameters setting concluded that balls to powder weight ratio are 20:1, the optimum ball mill working capacity is 2 L while the optimum speed of the ball mill is 105 rpm.

MoreBall Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1.

More2019-7-10 When the specification and rotating speed of the ball mill are fixed, the filling rate of the ball mill is in the range of less than 50%, and its production capacity will increase with the increase of the filling rate. Therefore, the first loading ratio of ball mill should be calculated according to this formula.

More2013-9-1 This was found to be true for all other factors investigated as well. With a size reduction ratio of 16:1 (Fig. 7a), the maximum capacity was obtained with a 50.8 mm/25.4 mm ball mix ratio of 90:10. As the size reduction ratio increases, the optimum ball ratio moves towards more small balls.

More2015-2-21 In practice, circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent. It may appear strange at first sight that the circulating load between a mill and classifier producing, for example, 100 tons of finished product per day can be as much as 400 tons or more, but this will be made clear by Fig. 71.

MoreBall mill capacity tends to increase with larger circulating loads, but this increase is restricted due to limitations in classification efficiency. Classification efficiency is defined as the percent of final product size material recovered to the classifier fine stream. In literature, there are several studies investigating the
