The camera was installed 3 mts away from the commercial sizer over the feed conveyor of the SAG Mill. This analyzer was calibrated following the manufacturer's procedure. The process characteristics are those of any normal working day: The T.V. analyzer ranges were adjusted to be the same as the ARMCO sizer: 1″, 2″, 3″, 4″.

The larger units can also be matched with the SAG mill in SAB/SABC configuration. Stirred mills (Regrinding). Finer regrinding or ultra-fine grinding is a frequent requirement in pilot plants and ALS has a range of units that can run continuously in pilot applications. The following mills are located at Balcatta: ISAMill tm, Deswik, and ...

SAG mills mimic the same shortcoming. It follows that in order to obtain the specifi c energy (SE) to achieve a certain transfer size, based on the 80 per cent passing value, an ineffi ciency factor must be applied to the SE of single stage ball mills, rod mills or AG/SAG mills when calculating power according to the Bond Third Theory method.

AG/SAG mill circuits. 30 years ago AG/SAG mill circuits were still almost exclusively sized using data from pilot test programs. These were both expensive and time consuming to conduct and necessitated the use of hundreds of tonnes of sample material. ... The target circuit throughput rate is 1000 tph. This material is then to be fed to a ball ...

After closed-circuit secondary crushing, the SAG mill feed 80% passing (F80) size was 25 mm to 30 mm. Installed grinding power is split equally between the two mills with the SAG mill fitted with a variable speed drive (VSD). SAG discharge screen oversize ('pebbles' or 'scats') was recycled through an 185 kW pebble crusher.
