· SAG Mill, HPGR and Ball Mill in an ABC Closed Circuit. Instead of recycling the larger size fraction, the oversize product from AG/SAG mills is sometimes prevented from discharging from the mill by using a reverse spiral at the discharge end and washes back into the mill for further grinding [4] .

In multi-stage ABC/SABC circuits, the AG or SAG mills are in closed circuit with screens and pebble crushers. The mill discharge from these mills consists of slurry, which goes to the ball mills for further grinding, and coarse pebbles/rocks, which are crushed and sent back to the mill.

Dec 02, 2016 circuit is shown in Figure1. It is commonly referred to as a SABC circuit, for Semi-Autogenous Ball mill Crusher SABC. This circuit shows a semi-autogenous grinding SAGball mill circuit where both grinding mills are in closed circuit, with the SAG mill closed with a crusher to control the amount of critical size material in the ...

2006). The laboratory bench-scale SAG mill reproduces operating conditions of a commercial SAG mill, in a closed circuit dry grinding environment. The ground product for the laboratory SAG mill is then submitted to the Bond ball mill work index test. The number of SAG mill revolutions required to grind the material to a P

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. …

We have sag mill and a closed circuit ball mill protable plant,AG/SAG millscan accomplish the same size reduction work as two or three stages of crushing and screening, a rodmill, and some or all of the work of aball mill. Because of the range ofmillsizes available, AG/SAGmilling can often be accomplished with fewer lines than in a conventional rodmill/ball mill circuit.

The SAG cyclone underflow passes through a flash flotation before returning to the SAG mill. A portion of the flash flotation tails reports to a separate ball mill which helps to reduce load on the SAG mill. Feed to the circuit is variable and comes from a range of …
