in a 6 ft. batch mill can be conclusive if the ore resembles ore previously tested. The third and most precise level of testing involves continuous milling in a 6 ft. x 2 ft. AG/SAG mill. Up to 50 ton samples are required for each ore type to be tested. The results of this test provide accurate information for the optimum mill sizing
The benchmark circuit varies with plant capacity and ore competency • Single stage crush/single stage SAG mills and two stage crush/ball mill circuits are typically selected for low throughput plants (<50 t/h) where personnel costs are a large component of costs. •
The ore is ground into a fine powder by large rotating mills. The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well.
Attrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill rock and a small ball charge ( 10 ) used in Semi Autogenous Grinding (SAG) mills balls of various sizes in Ball Mills and less commonly these days steel rods in Rod Mills.

Outotec asks for 10-20 carefully selected samples of each rock type representing the whole ore body for a first inspection test. These rock types may consist of ore marginal ore waste intermediate waste or SAG pebbles. Testing can be completed at the Tomra Mining test centers in Hamburg Germany and Sydney Australia.
Jun 14 2018 · In such a mill a grid with openings used for unloading crushed material is located in the unloading end of the drum. To crush the gold ore in order to obtain pure gold the large ore of gold is fed into a jaw crusher or mobile jaw crusher for the primary crushing process. The crushing process acts as a medium of screening the fine gold ore.
or stopping the SAG mill. Feed System Control Crushed ore is fed onto the feed conveyor using one or more variable speed feeders. The feeders are located under the ore stockpile or bins. By running different feeder combinations the size distribution of the SAG mill feed can be regulated (to some extent). The feedrate

SAG and ball mill with pebble crush SAG and ball circuits which cover the full range of ore types circuit types and equipment sizes as seen in Tables 1 and 2. AG and SAG mill pilot plant
Autogenous mills crush the ore without the need for iron or steel grinding media. They are used when the ore is hard enough for the tumbling ore to grind itself. In SAG milling 0.15 m 3 of 13 cm diameter iron or steel balls are added into the mill per 0.85 m 3 of ore (i.e. 15 vol.- steel ) to assist grinding. SAG mills are much more common.
ball mill index values for a given ore type (McKen Verret Williams 2006). On average the rod and ball mill indices are essentially equal but the ratio between the two can be quite variable. High RWI/ BWI ratios indicate competent ores with SAG Mill TestingTest Procedures to Characterize Ore
