An analysis of fine dry grinding in ball mills - …
INTRODUCTION It is well known that the dry grinding of cement and coal in tumbling ball mills becomes inefficient as the amount of fine powder in the mill becomes large. Hukki [I] has shown that the increase of surface area of cement (measured with the B.E_T. technique) per unit of energy input decreases as the material becomes very fine and, eventually, further grinding produces virtually no ...
