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 …

Different grinding experiments were carried out for all working parameters. Zircon beads with diameters of 3,36-2,00 mm were used as the grinding media. The effect of stirring speed during grinding was determined at different five speeds of 360, 540, 720, 1080 and 1440 rotation per minute against different times.
