It is a measure of the hardness of the ore from a SAG or AG milling perspective. The test is a batch test, run with 2 kg of ore in a standard 10 cm diameter by 30 cm long mill, and it measures the time (in minutes) required to grind a sample from 80% passing 12.5 mm to 80% passing 1.70 mm. The key to the scale-up applicability and widespread ...

 · The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...

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.
