Ball Mill Scale Up Paul O. Abbe®

The rule of thumb for mill scale up is approximately 1-(√D/√d) where d is the diameter of the smaller mill and D the diameter of the larger mill. So going from a 12" lab scale mill to a 24" mill, 1-(√24/√12) = 0.4, so the larger mill may perform as much as 40% more efficiently.
