For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.

gear driven mill, the motor speed is a function of the mill speed ⌽ RPM, and the gear ratio of the mill bull gear and the drive pinion. Case study No 1: Changing pinion on a fixed speed mill A common way of changing the speed of a mill that is driven by a fixed-speed motor is to change the pinion to a new design with an additional tooth.

SAG Mills and spares. SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. Attrition between grinding balls and ore particles causes grinding of finer particles.

Production in 2014 was impacted by the SAG mill bull gear failure. The copper grade was also higher in the 2015 first quarter over the comparable 2014 quarter. Copper production was up 93% in the current quarter compared to the March 2014 quarter. Mill throughput is on an upward trend and averaged 19,337 tonnes per day in March.

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 ...
