Then ball mill again for a few hours. Dump into another yogurt container, add a LITTLE water, then put into the compression die and press in the bench vise (because I am too cheap to buy the $80 harbor freight 6 ton hydraulic press). Let dry for a week (aka go back to work) then crush in a mortar with a pestle and grade. Because I am lazy, I ...

Ratio of work indices. If the rod mill (and crushing work index, to a lesser extent) are higher than the ball mill work index, then the circuit will probably require pebble crushing to operate efficiently. Desired transfer sizes. The transfer sizes displayed by the software are an instruction, and not a prediction.

Single stage SAG Mills are very beneficial in reducing CAPEX for plants with a staged throughput approach.
