Grinding & Classification Circuits

Another common issue with SAG mills is operating at very low density (e.g. <70% solids) - if there is room to increase SAG density, this will enable the SAG to grind finer with little or no decrease in throughput. Consider reducing the feed rate when the overload starts rather than waiting until a grind-out becomes necessary. If you are ...

AG

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). Therefore select a mill to draw at least 5440 Hp at the pinionshaft.

SAG vs. AG Mills: Understanding the Key Differences

SAG mills use a combination of steel balls and rock particles as grinding media, while AG mills use only the ore itself. Both types of mills are used for grinding ore in mineral processing operations, but SAG mills are larger in size and can grind larger quantities of ore. AG mills, on the other hand, are smaller and are typically used for ...

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.

SABC Grinding Circuit

The SABC circuit design is to accept minus 8″ run of mine ore from a 12,000 ton silo. Two Forano pan feeders discharge from the silo onto a 48″ belt which feeds the 32′ x 13.5′ mill. The mill is powered by two 5500 hp D.C. motors. Nominal mill speed is 10.7 r.p.m. (78% critical) with a top speed of 11.3 r.p.m.

Minerals | Free Full-Text | An LSTM Approach for SAG Mill

The LSTM network shows great results on predicting the relative operational hardness at 30 min time support. On SAG mill 1, using a lambda value of 0.5, the obtained accuracy was 77.3% while increasing the lambda to 1.5 led to an increase in accuracy of 93.1%. Similar results were found on the second SAG mill.

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:

What's the Difference Between Ball Mill, Rod Mill and SAG Mill?

Ball mill： Ball mills are the most widely used one. Rod mill： The rod mill has the highest efficiency when the feed size is <30mm and the discharge size is about 3mm with uniform particle size and light overcrushing phenomenon. SAG mill: When the weight of the SAG mill is more than 75%, the output is high and the energy consumption …
