## Mill Speed as a Manipulated Variable for Ball Mill

Afton claims that the variable mill speed has been useful for preventing liner wear while processing soft ore (Pazour, 1978). Sydvaranger processes iron ore through a 21 by 33-foot variable speed ball mill. The speed range of this mill is from 62 to 82 percent of critical, with normal operating speed at 78 percent. The manufacturer of this millSTEPPING FORWARD: USING VARIABLE SPEED DRIVES FOR,Variable Speed, Variable Speed Drive, Semi-autogenous mill, Ball mill, efficiency, drive system . INTRODUCTION . Comminution circuits for mining have evolved from basic circuits consisting of simple crushing machines to the current multistage, semi-autogenous (SAG) and ball mill circuits. This progression, however, has not always been accompanied by an improvement in the efficiency of

## Variable Speed SAG Mill

The single line grinding circuit at Bond Gold’s Colosseum mine consists of variable speed drive semi-autogenous (SAG) milling and secondary grinding with a fixed speed ball mill. There are several advantages and disadvantages of operating SAG mills with variable speed drives. Discussion in this paper will focus on the effects of variable speed SAG milling in relation to mill liner wearSAG Mill Variable Speed Drive,A variable speed primary mill provides a method of compensating for variations in ore hardness and gives a much more flexible grinding circuit. Although there is no such circuit on hand today, we think it is within our grasp the technology is there to make big mills, to use sophisticated control schemes and to vary the speed of huge hp mills. The economics remain to be proved, but we feel that
