NLS Inflow Pressure Screen
Application& Features
Inflow Pressure Screen is mainly used for fine screening before paper machine. It also has a slot screen basket. Automatic oil injection device, seal water detection alarm device ensure the safe running of equipment and reduce maintenance.
Working Principle
When the inner pressure screening equipment is running, the pulp with pressure which has’t screened, goes into the outer of screen drum. By means of pressure difference inside and outside, the qualified pulp under pressure through the slot hole into the sieve drum, and derives from the pulp at the bottom of the accepted pulp outlet. Impurities that can’t go through the slot hole fall to the bottom, and discharge out from the discharging pipe.
