Dec 31, 1993 Abstract. New results from a systematic grinding study with the larger, SM 320 Szego Mill are reported. A wide range of flow rates, from 750 to 5300 kg/h of coal, at 60-65% solids concentration has been covered, with both single and multiple passes through the mill. Particle size distributions and power consumption have been measured.

Raw coal (sometimes pre-treated) is fed into the centre of the grinding table. The grinding table rotates which causes the coal to move towards the outer periphery of the grinding table. The coal is ground between the rollers and grinding table. When enough coal has been reduced in size, it will flow over the top of the dam ring (retention ring).

PREDICTION OF PARTICLE SIZE DISTRIBUTION The coal is a very important raw material in the steel industry 6. It is extracted in the form of solids of con-siderable size and as such form may not generally be burned, sintered or gasi ed. So it must be properly com-minuted. Grinding of coal generally uses two types of crush-
