There had been a few attempts to relate their model with air flow through the mill, feed rate, feed size distribution, material filling and ball filling (Viswanathan, 1986, Zhang, 1992). Air swept ball mill model proposed by Austin et al. (1975) was validated by Apling and Ergin (1994) using the industrial scale data from a cement grinding circuit.

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., dâ†"V = 0.40 K√F dB = ball size (cm) F = feed size (cm)

Wet grinding of raw material batch is carried in ball mills of 20-100 Metric tons per day (Ball mill capacity depends on the production of the manufacturing unit), For wet grinding 30-50% water is added in the ball mill after addition of raw materials in ball mill.

the apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ ball mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ball mills designated as 5′ x 5′ where …
