What is the difference between a SAG mill and a ball mill? A SAG mill uses larger rocks or ore fragments as grinding media, while a ball mill uses smaller grinding media such as steel balls. Additionally, a SAG mill uses a minimal ball charge of 6 to 15%, while a ball mill requires a higher ball charge of 20 to 40%.
A: Yes, a ball mill can be used as a tumbling mill, but the reverse is not true. Tumbling mills are specifically designed for size reduction using a combination of forces, while ball mills are designed for grinding using impact and attrition forces.

In recent times, these mills have successfully replaced the conventional rod mill–ball mill configurations. In Australia, the number of AG/SAG mills increased from about six in 1984 to more than 40 in the following 5-year period [1]. The number of installations worldwide by mid 1989 was about 471, and presently the number is growing.

primary crushed ore enters the SAG or AG mill, gets ground to a "transfer size" where it exits the mill and is then passed to the closed circuit ball mill circuit. The SAG/AG mill product will usually contain a lot of finished product size, so it is useful to put the the SAG/AG product in the pumpbox that feeds the
Product Size: All passing 6 mesh with 80% passing 20 mesh. Net power from pilot plant: 16.5 KWH/ST. Mill, gear and pinion friction multiplier: 1.025. Mill Power required at pinionshaft = (240 x 16.5 x 1.025) ÷ 0.746 = 5440 Hp. Speed reducer efficiency: 98%. 5440 Hp ÷ 0.98 = 5550 HP (required minimum motor output power).
Mill (grinding) - Wikipedia. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of finer particles. SAG mills are characterized by their large diameter and short length as compared to ball mills.
As a general rule, SAG mills tend to be more expensive to acquire and maintain than ball mills, however, the cost-benefit analysis must consider the total cost of operation over the life of the mill. To get a closer look into quotes and details, you may find grinding mills here. Understand the Difference Between Ball Mill vs SAG Mill

In those days, 3 stages of crushing, and rod and ball mill grinding, were common in comminution flowsheets. Bond's Rod Mill Work Index (RM Wi) and Ball Mill Work Index (BM Wi) tests provided good designs for grinding mills. If the design was 1200 t/d, each stage had to be able to produce 1200 t/d or (54 t/h at 92.6% availability).

The Autogenous Mill, also known as AG Mill, is a type of grinding mill used in the mining industry. This machine uses ore and rock itself as grinding media to perform its job. Unlike other types of mills that use steel balls or rods for grinding materials, the Autogenous Mill relies on the material being ground to break itself into smaller pieces.
