SABC Grinding Circuit Operation & Optimization

When operating a grinding circuit (at Granny Smith) under a wide range of conditions: campaigning very competent underground ore followed by soft oxide, primary versus secondary crushed feed and finally single-stage SAG and conventional SAG, ball mill and pebble crusher (SABC) configurations. Economics changed and a review of the circuit performance including modelling and simulation resulted

Selection oof Comminution Circuits for Improved Efficiency

• 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. • SAB circuits are typically selected for plants of 0.5 to 2 Mt/a. • SABC circuits are typically selected for plants above 2 Mt/a treating moderate

AN OVERVIEW OF SINGLE STAGE AUTOGENOUS AND

The grind size is more difficult to control in a single stage SAG circuit at fine target grind sizes, when compared to an SAB or SABC circuit. Based on an understanding of the effect of grind size on a single stage operation, this paper discusses why this has been the case, and will attempt to define general rules regarding the

Raw Bond Model. This is a SAG or AG mill plus ball mill model that estimates the specific energy consumption (E SAG) using the 1979 Barratt equation and the classical Bond work index equation including Rowland efficiency factors.The model allows a manual calibration factor on both equations (CF SAG and CF ball, respectively).This formula usually gives higher total circuit specific energy

If grind sensitivity is an issue or the capacity is too high for a single SAG mill, a two stage grinding circuit is recommended.
