· This is important because it was found that there was a 1–1.5 kWh/t higher ball mill work index if the –3.35 mm ball mill test feed size is obtained by SAG mill grinding compared with crushing. The correlation between the SAGDesign number and the full size SAG mill pinion energy was determined to be linear and of the form (3.29) E SAG = Revs 16,000 + M 447 .3 M …
· Thread sizes are given in nominal sizes, not in actual measurement. For instance, when a screw or bolt measures 5.9mm, it is called a 6mm thread. There are two common methods to write the thread dimensions. 1.Thread sizes in inches are specified by diameter ...

The effect in this job is better ...
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5). Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral ( Chapter 12 ).
