Analysis of grinding of pelletized wood waste with the Szego Mill

Fig. 2 is a plot of this type for grinding of Energex™ pelletized wood waste in the pilot-size Szego Mill. The data appear in a band which is concave upwards and narrows to an apex approaching the horizontal axis. Boundaries have been drawn enclosing the data, the lower boundary being the locus of results of the most efficient runs, i.e., …

Grinding of coal-oil slurries with the Szego mill

Grinding of coal in fuel oil for coal-oil mixtures (COM) preparation is simpler and may give better slurry properties than dry grinding followed by dispersion in oil. A 42 weight percent slurry of 600–840 μm particles of Pittsburgh coal in #2, #4, and #6 fuel oils has been ground with the novel Szego mill. Particle size distributions at different residence times are …
