Jul 31, 2014· Mill power draw prediction can be carried out using Morrell''s power model for tumbling mills (Morrell, 1998). Bond method The established technique for determining power requirements for ball mills is the Bond method (Bond, 1961). This method also involves the application of some ''efficiency factors'' as described by Rowland (1975).
zIt was additionally shown that the ballmill dimensions predicted from the above methodology are almost equal to those of the Bond method. This fact is very important, because the various corrections, associated with the Bond methodology, are not necessary and the model developed can be used as an alternative method for ballmill scaleup ...

Design Method of Ball Mill by Discrete Element Method The grinding rate of gibbsite in tumbling and rocking ball mills using fins was well correlated with the specific impact energy of the balls calculated from Discrete Element Method simulation. This relationship was successfully used for the scaleup of a rocking ball mill, and the optimum ...
The operating principle of the ball mill consists of following steps. In a continuously operating ball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
