Wet grinding of coal in the Szego Mill (Conference) OSTI.GOV

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.
