Ball Mill Scale Up
The performance and efficiency of ball mill generally improves with increasing diameter. All other factors being the same including media size, percent of critical speed, product loading, etc. 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. The inverse will be applicable to scaling a mill down to a smaller diameter.
