Modeling and Control of Coal Mill ScienceDirect

Mumbai, India The pressure drop, across the mill depends on the mill differential pressure of the primary air, and the amount of coal suspended in the air. 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.
