Ball mills give a controlled final grind and produce flotation feed of a uniform size Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills dry basis is typically 75 vol ore and 25 steelGet Price
Generally filling the mill by balls must not exceed 30–35 of its volume The productivity of ball mills depends on the drum diameter and the relation of ∫ drum diameter and length The optimum ratio between length L and diameter D L D is usually accepted in the range 156–164Get Price
Ball Mill Filling Degree At constant ball filling degree this mills performance increases as the pool angle and dry ball angle go toward zero To recap the dry head angle is the difference between the ball head and pulp head angles and the pool angle is the difference between the ball foot and pulp foot angles Get PriceGet Price
The results obtained from this work show the ball filling percentage variation is between 12– 37 which is lower than mill ball filling percentage according to the designed conditions 15 In addition acquired load samplings result for mill ball filling was 13 KeywordsMiduk Copper oncentrator SAG Mill Ball Filling PercentageGet Price

The performance of ball mills is very sensitive to the volumetric mill filling which influences grinding media wear rates throughput power draw and product grind size A pilot plant investigation with an overflow mill discharge has been conducted For a given throughput it seems that the pool size has a major influence on the product grindGet Price
Figure 85 Effect of mill filling on power draft for ball mills The data is taken from Rexnord Process Machinery Reference Manual Rexnord Process Machinery Division Milwaukee 1976 The effect of varying mill speed on the power drawn by the mill is shown graphically in Figure 84 The speed of rotation of the mill influences the power draftGet Price
