Pressure Screens

Fluid-Quip pressure screens are designed for efficiency and simplicity in liquid-solid separation of fibrous non-abrasive materials and for ease of operation, to simplify maintenance and to reduce down time.

These Fluid-Quip 120° Pressure Screens consists of a cabinet with a specified number of compartments, each enclosing a single screen, supplied by three to five (3-5) nozzles connected to a feed header. Valves on the feed header control slurry flow. Slurry pumped into the header manifold @ 60 psi (413 kPa) is directed through the feed nozzles at a tangent onto the 120° screen. As the slurry flows downward, the screen’s bar edges slice off thin layers that pass through the slot opening to the filtrate port. Slurry material larger than the slot openings is retained on the screen surface and flows downward to the “oversize” port.

By varying feed pressure, nozzle orifice size, and the open area of screens, operating conditions can be customized to meet specific product requirements. Fluid-Quip can assist customers in determining the conditions that best fit their needs.

Fluid-Quip pressure screens are used for third grind dewatering, with 50-micron screen openings and ¾” feed nozzles for grind rate capacities up to 12,000 bpd (300 MTPD) per screen surface.

For the first stage fiber wash, one Fluid-Quip triple pressure screen should be used for every 15,000 bpd of grind rate. For stages, 2 through 6, one Fluid-Quip triple pressure screen should be used for every 45,000 bpd.

For the fiber dewatering screen, one Fluid-Quip triple pressure screen should be used for every 45,000 bpd of grind rate.

Fluid-Quip pressure screens are used, with 150-micron screen openings and ¾” feed nozzles for grind rate capacities up to 16,000 bpd (400 MTPD) per screen surface.
