feeding size mm ball mill

calculation of maximum ball size in mm for ball mill

Feeding 15mm to a ball mill this size is not typical - much larger ball mills (21 or 7.0m diameter) typically get 12-16mm feed (from what I have seen in my experience) With regards to 3.5- 4 media, typically for Ball mills of this size (16), max size of ball used should be around the 50-60mm. 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, i.e., dV 0.40 KF dB ball size (cm) F ...

Jun 01, 2018 Fig. 5 shows the variation of size class 1 (M1) with the milling time for the two feed size distributions. For this coarser feed the 50 2010 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. Calculation of maximum ball size in mm for ball mill grinding. Sep 01, 2013 As the feed size is reduced further, less of the 50.8 mm balls and more of the 25.4 mm balls are required for the maximum capacity, attaining 100% of 25.4 mm balls for a feed size of 4.7 mm (Fig. 6d).
