Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach. When future tonnage is to be increased, the SAG Mill can feed downstream ball milling to boost capacity. Fuller-Traylor SAG/AG Mills range in size from 4.3m through 12.2m in diameter with powers as high as 28,000 kW.

Mill Liners Foundry. SAG and ball mills grind material during different activities and usually are implemented in different phases of the practice. SAG mills normally have a bigger diameter compared to span and are utilised to reduce huge feed size ore (an average of ~300mm) right down to ~3mm, regularly for additionally grinding . More

Grinding Mill Specifications Data. According to formula 42.3/√d, where d is equal to internal shell diameter within new liners. In this case the thickness used was 60 mm for small mill sizes up to and including 2940 and 80 mm for larger mills.

sag mills instance; Toromocho – A giant in high-altitude mining. The three gearless mill drive (GMD) systems are the ABB most powerful ever made. The GMD for the 40-foot SAG mill has a power rating of 28 megawatts (MW), and the GMDs for the two 28-foot ball mills have a power rating of 22 MW.

He notes that the traditional use of steel liners in large SAG mills presents a number of challenges. For instance, there may be bending stress inside the steel liner due to inexact fitting on the mill's curved surface, and the higher rigidity of steel, compared with rubber, makes it less than optimal for absorbing the energy of rock material inside the mill.

The slurry level in AG/SAG and ball mills has an influence on their power draw, which in some instances can be profound. This is particularly the case with so-called slurry pooling in AG/SAG mills which can result in significant lowering of power draw.

SAG mills grinding media includes some large and hard rocks, filled rate of 9% 20%. SAG mill grind ores through impact, attrition, abrasion forces. In practice, for a given ore and equal processing conditions, the AG milling has a finer grind than SAG mills.

For instance, the mill performance could become worse or better by putting in a new shell liner. Data from pilot plant test work illustrates the influence of the shell lifting effect on the grind for a primary grinding duty. Figure 5 shows the evolution of the.

SAG mills have a higher installed power density for a given plant footprint relative to AC mills. With the combination of finer grind and a lower installed power density (based on the lower density of the mill charge), a typical AG mill has a lower throughput, a lower power draw, and produces a finer grind.
