This pressure drop, which ranges from 25 to 30 inches of water column, keeps changing as the gravimetri-cally controlled feedrate to the mill fluctuates. Despite these pressure-drop fluctuations, the mill’s pneumatic con-

Modeling and Control of Coal Mill ScienceDirect

2013-12-1  During normal operation, the mill pressure drop is predominately proportional to the primary air differential pressure and a small change in coal mass does not affect the pressure drop significantly. Also, when the coal mass becomes zero, the pressure drop also becomes zero. These conditions are guaranteed by the term .
