Large Ball Mill Scaleup Factors To Be Studied Relative To Large Ball Mill Scaleup Factors To Be Studied Relative To

Abstract. Ball mills 5.5 m 18 ft in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills particularly when the large mills carry 40 by volume ball charges. This paper will explore factors used in scaling up ball mills showing where the advantages of one factor can possibly be negated by another factor.

A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. The principal use for rod mills which were invented to make ball mill feed in a wet-grinding rod mill-ball mill circuit. Rod mills came into use in the United States beginning in 1900s and .

Effects Of Percent Solids And Mill Loading On Ball Wear In Effects Of Percent Solids And Mill Loading On Ball Wear In

The effects of percent solids mill loading and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of 44- m 325-mesh material reached maximum at 70 solids whereas the ball wear decreased as pulp density increased. HCLA steel balls ground the taconite ore finer than mild steel balls
