Wet grinding of coal in the Szego Mill (Conference)

Laboratory froth flotation tests were conducted with dry- and wet-ground minus-400-mesh coal to determine the effect of grinding methods on clean coal recovery and product grade. A laboratory air-classifying impact mill was used for the dry grinding, and a stirred ball mill (attritor) was used for the wet grinding. Products of as near the same size distribution as possible were prepared by ...

For the mine size coal at 20% minus 200 mesh, the data show that somewhat more rock dust is required to prevent explosions in the LLEM than in the BEM. The reason may be that the LLEM is more adiabatic than the BEM because of the larger cross-sectional area at the LLEM. ARTICLE IN PRESS Fig. 1.

Crumb Rubber - Scrap Tire News: Tire and Rubber

This process reduces the rubber to particles ranging from 1/4 inch minus to 30 mesh, with the majority of the particle distribution between 1/4 inch minus and 20 mesh. A typical throughput is 4,000 to 6,000 pounds per hour. Cryogenic grinding avoids heat degradation of the rubber and produces a high yield of product that is free of almost all fiber or steel, which is liberated during the process.
