Geometry and loading
Specify the target cut size, solids concentration, panel span and flow direction. Slot width alone does not determine capacity: the profile, open area, support spacing and wear allowance influence service life.
Construction choice
Flat panels, framed panels and screen cylinders suit different machines and mounting systems. Material selection follows abrasion, corrosion and cleaning exposure rather than a standard grade alone.
Information for quotation
Send the existing screen drawing or sample, slot width, panel or cylinder size, frame details, support positions, operating load, quantity and replacement interval. Photograph wear patterns if quoting a failed screen.
Design review
Panel span, slot orientation, support spacing and abrasion allowance are as important as nominal opening in a dewatering screen. Flat, framed and cylindrical forms fit different machines. Specify the solids distribution, loading, flow direction, vibration or impact exposure, attachment pattern and replacement method before selecting a screen form.
Inspection and acceptance
A worn sample helps identify failure location but may no longer represent original dimensions. Use the machine seat or controlled drawing for fit, then compare opening and support geometry on a trial part. Throughput, wear life and cut size need field conditions for validation; a larger theoretical open area alone is not proof of better duty performance.
Separate screen shape from machine motion
A flat panel spans a support opening. A sieve bend has a defined curved face and tangential feed. A centrifuge basket belongs to a rotating assembly. These forms require different mounting and discharge details; the common wedge-wire surface does not make them interchangeable.
For the curved panel, retain radius, arc, width and inlet tangent. For the rotating basket, retain both end geometries, locating datums, runout and balancing requirements. Record abrasion, solids loading and cleaning with each selected construction so replacement screens preserve their original machine interface.
