DESIGN OF THE KUBAKA GRINDNG CIRCUIT USING SPI AND BOND

The selection of ball mill design criteria was much more straight-forward than for the SAG mill. Bond work index testing using a 200 mesh closing screen was done on 7 samples as listed above. The median hardness for these samples was 15.5 kWh/t and that is the value chosen by Davy for ball mill design.
