07 So/id fuels (preparation) modifiers for the coal particles. The agglomerates were smaller and more hydrophobic. The clean coal recovery increased substantially with a lowering of the ash content for these type of coals. ## 97104414 Mill power for high-pressure grinding rolls in coal grinding Austin, L. G. Miner. Metall. Prowss.. 1997. 14, (3). 18-26. For six coals and a crystal quartz, the grinding force, gap dimension mass flow rate, and net mill power were measured using an instrumented laboratory high-pressure grinding roller mill. A technique was developed to estimate the compressive stress-strain curves for compression of the materials in the mill plus the effects of elastic decompression. To reconcile the mill power and grinding pressure results, it was necessary to allow for energy recovery on decompression. Between the form of the stress-strain curves or the variation of specific mill power factor and the Hardgrove grindability index (HGI), no clea correlation was discovered, but coals with the lowest and highest HGls gave significantly different results to the other coals. Feeds < 140 mesh flowed more rapidly than coarser feeds and would not build up high grinding press
