Exploring ball size distribution in coal grinding mills

May 01, 2014 It has generally been established by many researchers that grinding efficiency for a given size distribution is to some extent dependent on ball size,,,and from Ref. it has been established that ball diameter (d) relates to a and μ as follows: (14) a = K 1 d N 1 and μ = K 2 d N 2 where Austin et al. found that N 1 ≈ − 1 and N 2 ≈ 2.

Exploring ball size distribution in coal grinding mills

The amount and ball size distribution in this charge, as well as the frequency with which new balls are added to the mill, have significant effects on the mill capacity and the milling efficiency. Small balls are effective in grinding fine particles in the load, whereas large balls are required to deal with large particles of coal or stone
