Wedge wire screens
Wedge wire screen panels, cylinders and baskets combine a defined slot with a welded profile-wire support structure. Match the working face, slot direction, exposed area and support span to separation, drainage or equipment protection.

Construction
How we build the screen
- Opening fractionFor parallel slots, fraction = slot / (slot + wire face width). A 0.50 mm slot and 2.0 mm face give 20% before rods, margins and blocked zones.
- Slot taperA widening passage behind the narrow working opening can reduce particle wedging. The intended working face must face the incoming flow.
- Rod layoutCloser support rods shorten the span but occupy area. Include differential pressure, span and mechanical loads in the structural design.
- Slot orientation and supportsShow the slot direction against the feed path, support-rod direction and mounting points. Allocate the clear panel span or cylinder support spacing on the finished drawing.

A slot is an opening within a load-bearing structure
Profile wire and support rods perform different jobs. The narrow opening at the working surface defines the slot, while the profile widens the passage behind that face. Slot width and wire face width together set the repeating pitch; rods, frames and blank margins occupy part of the finished screen area. Read these dimensions together when comparing screens.
A flat panel carries loads between its fixing points. A cylinder places the screen around a process flow path, and a basket joins the screening wall to a base and handling structure. Keep each product geometry linked to its actual duty. Dewatering, resin retention and liquid straining use different feed conditions and maintenance arrangements.
Fit the screen to its flow path and maintenance access
Mark the feed side and discharge side on the drawing. The selected wire and support arrangement establishes the working face; the cylinder shape alone does not define flow direction. Include pressure difference, reverse-cleaning loads and the position of supporting rings or rails in the installation specification.
Provide access to remove retained solids and inspect the working face. Connections, sealing lands and lifting features belong to the assembled component. The slot guide supports opening selection; the specification worksheet connects that selection to dimensions, materials, supports and inspection points.

Applications
Continuous-slot panels, cylinders and baskets serve solid retention, dewatering, resin retention and process-liquid straining. Select each geometry for the feed, discharge and mounting arrangement.
Media retention
Keep resin or other process media inside vessel internals.
Dewatering
Drain liquid from retained solids on panels.
Intake cylinders
Provide screened area around inlet or distributor assemblies.
Inspect slots on the working face
Check the useful surface, including edges and joints.
Slot width

Wire and rods
Check profiles, support spacing and weld continuity.
Installed form
Check flatness or roundness and identify the working face.
Finished working face
Check slot consistency at the working surface, wire-to-rod welds, blank margins and overall geometry. Record the screen orientation and its installed support positions.

Questions before ordering
How is a 0.10 mm slot specified?
A 0.10 mm slot defines a geometric opening of 100 µm at the working face. State the slot tolerance and flow orientation with it; use the specified retention test to define particle separation under the process conditions.
How is reverse cleaning designed?
Define the reverse-flow direction, pressure difference and cleaning sequence. Select the profile, support structure and joints for those loads and record the supported working face on the drawing.
How is slot width balanced with capacity?
Select the opening for the retained solids, then calculate clear-slot area with the chosen wire face and supports. Size the exposed screen surface and cleaning interval together with the required flow.
Does a cylinder always filter from outside to inside?
Flow direction follows the profile-wire orientation and support design. The drawing identifies feed side, discharge side and cleaning direction for the supplied cylinder.
What distinguishes screen area from open area?
Screen area is the exposed screening surface. Open area is the sum of its clear slots after accounting for profile width, supports and blank zones; use the installed geometry for sizing.
