Segregation patterns of various mills have never been reported and compared in the literature. Therefore, the investigations of component segregation are of great value and necessity. In this paper, three representative pulverizing systems were utilized to grind the same raw coal into three groups of superfine powder.

Ball mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed circuit system, with oversize material continuously being re-circulated back into the mill to be reduced.

A survey of 40 industrial mills in China found that the maximum ball mill diameter in use was 7.9 metres and length 13.6 metres. Autogenous mills range up to 11 metres in diameter. The length-to-diameter ratios indicated in Table 1 for ball mills are for normal use, but for primary grinding the ratio could vary between 1:1 and 1.8:1.
