A Systems Approach to Pressure Screen Control in the Pulp Mill Aprocess control strategy for operating pulp millpressure screens improued paper machine efficiency The purpose of a pulp mill pressure screen is to fractionate the feed stream fiber screen differential pressure DP 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
