EFFECT OF BALL SIZE DISTRIBUTION ON MILLING When a ball mill is running at low speed grinding is a result of rubbing action within the ball mass and between the ball mass and the mill liners The size reduction depends mainly on the surface areas of the media in interaction Hukki 1954 This breakage mechanism is known as attrition Get Price

break The breakage rate is also affected by the reduced capture probabilities of fine particles in mills [12] This suggests that the breakage rate increases with increase in particle size However, for too large particles that cannot be correctly nipped and fractured by the balls, the rate of breakage steadily drops and tends to zero

06-06-2016· Higher ball charges shift the breakage mode away from attrition and abrasion breakage toward impact breakage; as a result, AG milling produces a finer grind than SAG milling for a given ore and otherwise equal operating conditions The following circuits are common in the gold industry: Single stage AG/SAG milling
