THE OPTIMAL BALL DIAMETER IN A MILL

2012-5-15  The basic condition, which must be met while grinding the material in a mill is that the ball, while breaking the material grain, causes in it stress which is higher than the grain hardness (Bond, 1962; Razumov, 1947; Supov, 1962). Therefore, for the biggest grain size, it is necessary to have a definite number of the biggest balls in the charge,
