Polywedge Screen Panels – A Precision Screening & Dewatering Solution

The polywedge screen panel is a composite screening medium. It consists of uniformly spaced wedge wires welded into a screening surface, externally encapsulated with a polyurethane protective layer or supported by a polyurethane frame. This design combines the high open area and drainage efficiency of polyurethane with the exceptional wear resistance of wedge wires, significantly enhancing overall abrasion resistance, corrosion resistance, and service life. It features uniform slot openings, excellent wear and corrosion resistance, and excellent dewatering and desliming performance, making it highly suitable for applications demanding both screening precision and durability in challenging operating environments.

Features

Non-clogging. The continuous slots formed by V-shaped profile wires ensure minimal contact between particles and the slot, effectively minimizing clogging.
High filtration accuracy. The opening gap is precisely controlled, making it suitable for applications requiring high screening precision.
Easy to clean. The screen can be easily cleaned by scraping or backwashing.
Durable structure. Each intersection of the profile wire and support rod is welded, resulting in a more robust structure.
Flexible application. A variety of sizes and slot configurations are available to accommodate different equipment structures and process requirements.

Applications

Polywedge screen panels are widely used in dewatering screens, vibrating screens, and similar equipment in coal preparation plants, coking plants, mines, power plants, dredging companies, metallurgy, petroleum, petrochemical, and related industries.
