SAG Mill Grinding Circuit Design
Difference Between Sag Mill vs Ball Mill
1. SAG mill is the primary tool for grinding. SAG mill is used before the other mills. Ball mill is a secondary, and it is used after the SAG mill. 2. SAG mill breaks the raw material into pieces for the further grinding. Ball mill is used to grind the pieces of raw material into. powder-like structures. 3.

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).
PRE-CRUSHING OF SAG FEED: FRIEND OR FOE
The SAGDesign test and design equations give the energy to grind an ore from 80% passing 152 mm to 80% passing 1.7 mm. Since this transfer size is fine enough feed for a ball mill no ball milling inefficiencies will occur. A 5 mm closing screen will deliver this approximate size of SAG ground product to the ball mill.

Pre-Processing to Increase the Capacity of SAG Mill …
Simulations indicated that a capacity increase of 12% would be achieved in the existing grinding circuit by further crushing 35% of SAG mill fresh feed. Such figures would represent yearly additions of 8.3 kt in copper and 250 kg in gold productions. Study. Minerals 2022, 12, 727.
Semi Autogenous Grinding Mill
A high aspect SAG mill had an ID of 6.0 m and the length measured 4.0 m along the central line. The mill was charged with ore having a S.G. of 2.65 and the load was 40% of the mill volume. The grinding media steel balls occupied 12.2 % of the mill volume. The mill was rotated at 75% of its critical speed, which was 12.9 rpm. Estimate:1.
Autogenous and Semi-autogenous Grinding Circuits
Often an existing plant that observes their SAG mill is limiting throughput, but the ball mills are under-loaded can open-circuit the primary mill to better balance the grinding load with the secondary mill. The coarse transfer size to the ball mill makes this circuit unsuitable for most fine-grinding applications such as gold ores ...
