Reagglomeration phenomena in fine dry grinding of coal
1997 5 1 Abstract. 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. Nhận giá
