Following this rule of thumb, the number of grinding balls for each ball size and jar volume is indicated in the table below. To pulverize, for example, 200 ml of a sample consisting of 7 mm particles, a 500 ml jar and grinding balls sized at least 20 mm or larger are recommended. According to the table, 25 grinding balls are required.
Fig. 5 shows the effects of varying makeup ball composition on the amount of M2 produced for different flow rates in cubic metres per hour. The mill under study has the maximum ball diameter of 40 mm [11]. In this research, the size combinations used were 50 and 40 mm, 40 and 30 mm, 30 and 20 mm and lastly 20 and 15 mm.

where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/ = % of critical speed. If 100 mm dia balls are replaced by 50 mm dia balls, and the other conditions are remaining the same,
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 % of the mill volume and its size depends on the feed and mill size.
