Inflow pressure screen
The equipment is used for fine screening before paper machine. It is also used for screening the chemical pulp and waste paper pulp.
Stock enters the screen chamber through a tangential inlet and begins a circular travel a
round the outside of the screen basket. The motion of the inlet-side hydrofoils accelerates the circular flow, which immediately separates and moves heavy contaminants away from the screen plate as the debris travels along the casing wall to the reject opening.
The accepts flow is downward trough a continuous opening located below the screen basket inward-flo and the accepts compartment design maintain a constant flow profile throughout this critical zone.
The hydrofoils rotating around the outside of the basket lift impurities away from the screen basket. These rejects are then held away from the screen basket by centrifugal force in their travel to the reject outlet. Reject materials are processed by succeeding stages of inflow pressure screen with slots for efficient fiber recovery and positive removal of fine debris.
