A high aspect 36ft Ø x 18ft EGL, 13 MW SAG mill with recycle crusher was selected for the single stage SAG mill configuration. This design is in line with the selection dictated in Table 2. The owner understood the circuit selection had some technical risk associated and set about mitigating these points during design and project readiness.

STARTLING EFFECT OF BALL SCATS REMOVAL ON SAG MILL PERFORMANCE. In order to measure the ball load in the mill, the feed to the mill was stopped and it was ground out to a ball charge only As a result of slurry pooling in the mill, the surface of the charge could unfortunately not be inspected, and the 97 ball level was measured relative to the slurry, 398mm below it...

Features. Semi-autogenous Outotec SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.

Slurry pooling, excessive accumulation of slurry in the mill, and the associated loss of throughput and grind, are well recognised on lowaspect, single-stage SAG mills. However, it is becoming apparent that a wide range of the high-aspect mills also suffer from pooling issues. This is associated with the high throughput of mills treating less competent ores, excessive pebble …

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 ...
