High recirculating loads in Ball Mill Circuits

Screens have proved that circulating loads can be reduced to 100%. Unfortunately most cyclones will report high percentages of fines back to the ball mill resulting in high recirculating loads. Applying a more efficient separation technology, circulating loads are not only reduced, but in many cases where multiple mills are installed, are idled.
