The foundations for the Ball and SAG mills were prepared with concrete and grout works, as well as anchor bolt and sole plate installation. The Ball and SAG mill shells were recently delivered, and are now being assembled and prepared for installation. The Company expects delivery of remaining mill components such as the motors in the near term.

SAG mills generate higher levels of impact reduction and ball mills higher levels of abrading action. A mill lining system serves two purposes: to protect the mill shell from wear caused by the impact and abrasion of the mill charge, and to elevate and tumble the mill contents in the necessary manner to create a grinding action.

The final plan was to increase the ball charge in the SAG and ball mill to 10% v / v and 27% v / v, respectively; set the upper limit of the operating power in the ball mill to 5800 kW; use a TC Series crusher (without a power-/feed rate–controlling device, but with a feed bin) to crush pebbles for recirculation back to the SAG mill feed ...

The grinding circuit consists of a SAG mill, ball mill and cyclones. The grinding circuit will be designed to reduce ore from an 80% passing size of 76mm to 40µm. The SAG mill will be a single pinion low aspect mill, operating in a closed circuit. The mill has an inside diameter of 3.8m and an effective grinding length (EGL) of 5.0m. The mill ...

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 ...

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
