Drying capacity of an Air Swept Ball Mill? How much?

Hi again guys!!

I will follow with a more complicated question

I use to apply the rule: in 1m3 (of ball mill) use to dry 150kg H2O (moisture in the feeded material). It works well.

Now the problem arrives when I want to use an Air Swept ball mill. So, anybody could tell me an average/normal value of the amount of H2O an AS Ball Mill could dry? (knowing that the gas speed in an air swept mill is much more)

Thanks!!!! ■
