Investigations were performed on fine grinding of bituminous coal in a laboratory-scale pulverizer. The results indicated that the breakage behavior at relatively coarse sizes (i.e., greater than about 20 µm) is essentially "normal." However, at fine sizes (i.e., less than about 10 µm), there is clear evidence of reagglomeration. A simplified population-balance model for …

factors can affect the grindability and drying in the mill. The grinding test conditions are shown in Table 3. For the evaluation of mill operation performance with high-moisture coal, three different coals with moisture contents of 45%, 50% and 55% were applied, and drying capacity and mill operation stability were verified in the test.

Abstract In this study, experimental data for wet- and dry-ground coal samples under wet and dry grinding are characterized by commonly used distribution functions. First, both the R-R and Swrebec functions have superior fitting performances for cumulative particle size curves compared to the other studied functions. On this basis, a time-dependent expression is drawn …
