Wet grinding of coal in the Szego Mill (Conference)

1993-12-31  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.

Particle Shapes Produced by Comminution in the Szego

1995-6-1  The shapes of particles produced by comminution in the Szego Mill, a planetary ringroller mill, in different coal grinding operations show that particle shape is dependent on the type of operation, and help explain the breakage mechanisms. Dry grinding produces particles with a low aspect ratio due to interparticle attrition; significant briquetting of fine particles may

2002-2-12  In order to grind coal in the same Szego Mill, water must be present in a ratio of 0.4. If there is insufficient water present, the mixture will be too paste-like and will not be acceptably handleable in the Szego Mill. In the other mills which do not have the same transport capability of the Szego Mill, even more water would be required.
