Forum on the Non-Cataracting Ball Mill

CIM Bulletin, 1958

L. E. DJINGHEUZIAN, Forum Chairman

ANON-CATARACTING (N-C) ball mill is so operated that the balls are not thrown inward at the top of their paths . The result is to maintain, in the mill, a quiescent pool in which classification will occur at a limiting size corresponding to the pulp density. N-C operation is produced by effecting proper relationship among mill speed, ball diameter, volume of ball load, and pulp density. Such operation is typified by the primary ball-mill operation of the Tennessee Copper Company, Copperhill, Tenn., and the Cleveland Cliff Iron Company, near Ishpeming, Mich
