Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in ...

Grinding is one of the most important and expensive steps of mineral processing. Therefore, different types of grinding mills such as rod mills, ball mills, semi-autogenous (SAG) mills and autogenous (AG) mills can be utilized for comminution of mineral ores [].Up to today, SAG mills and AG mills have been widely used to reduce operation costs and increase throughput.

Introduction: According to the different ball filling rate in the mill cylinder, it can be divided into autogenous mill and semi autogenous mill; in order to eliminate the influence of hard rock accumulation, autogenous mill is allowed to add about 3% big balls (φ 80 ~ φ 120), and the ball filling rate of semi autogenous mill is generally 8% ~ 12%, very large up to 15%.

For instance, at Lornex Mining, one of the most successful SAG installations, the ball load varies normally from 6-7% by volume of the mill; the ball make-up consists usually of 80% 4-inch diameter balls and 20% 5-inch diameter balls. The ratio of the larger balls is increased when the mill is processing hard ore and decreased with soft ore.
