In practice, circulating loads between ball mills and classifiers are rarely less than 200 per cent and frequently exceed 700 per cent. It may appear strange at first sight that the circulating load between a mill and classifier producing, for example, 100 tons of finished product per day can be as much as 400 tons or more, but this will be ...

Pilot-scale testwork based on a 6' x 2' mill is arguably still the most reliable method for predicting full scale autogenous (AG) and semi-autogenous (SAG) grinding mill behaviour when treating a given ore. However, the cost of a detailed pilot-mill programme both in terms of providing sufficient sample material as well as the

optimization was also part of the study. F80 is 25-30 mm for maximum throughput rate. Ball charge in the SAG. mill is maintained between 12 % and 15.5 % depending on the feed size. This paper describes the performance of the St. Ives grinding circuit and ore hardness. SAG discharge slurry passes over a vibrating screen.

For example, assume that raw ore is a two component system comprised of a valued mineral and host rock having relative densities of 6.30 and 2.65, respectively. The amount of valued mineral is 30% of the total ore.Total Solid Mass, M: Mineral + Host Rock – 30 + 70 = 100 Total Volume, Vs: Total Solid Relative Density
A wet grinding ball mill in closed circuit is to be fed 100 TPH of a material with a work index of 15 and a size distribution of 80% passing ¼ inch (6350 microns). The required product size distribution is to be 80% passing 100 mesh (149 microns). In order to determine the power requirement, the steps are as follows:

SAG Mill Trommel Screens The SAG mill trommel screen provides a simple mechanism to classify large volumes of mill product. Many designers and mill operators believe that the benefits of simplicity and the ability to handle throughputs in excess of 5 000 tph of solids make trommels the preferred equipment for this application.
Key benefits. High reliability – over a century of experience with 4000+ ball mills installed globally. Large through-flow area ensures low pressure drop across the mill. Horizontal slide shoe bearing design allows much simpler foundations and reduced installation height. Increased effective grinding area with Stanex diaphragm design.

Reducing the F80 (80% of the feed size) to the SAG mill by 10mm will result in a 3-6% increase in SAG mill throughput, with the magnitude ...
Control of -SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).
