excess air in raw mill. hello, we use a ball mill for raw material grinding with central discharge, the problem arises with the difference in volume flow of air at NTP between the inlet and the outlet, for eg at the inlet we have a volume flow of 33000Nm3/hr, the out let volume flow comes around to almost double this value around 70000Nm3/h. what is the reason for this sudden difference
