Polywedge Screen Panels

Polywedge Screen Panels

(Polyurethane Framed Wedge Wire Screen Media)

Polywedge Screen Panels are a premium composite screening media that combines the high open area and superior drainage performance of stainless steel wedge wire with the wear resistance and noise reduction advantages of polyurethane framing. Designed for demanding mineral processing applications, Polywedge panels are widely used in coal preparation plants, dense medium recovery circuits, dewatering systems, and fine particle classification processes.

Compared with conventional polyurethane screen panels or all-metal wedge wire screens, Polywedge technology offers an optimized balance between screening efficiency, service life, and maintenance costs. The precision profile wire structure delivers excellent drainage performance and minimizes material blinding, while the polyurethane frame provides outstanding impact resistance and simplifies modular installation.

Polywedge Screen Panels are particularly suitable for high-capacity screening operations where accurate cut size, maximum throughput, and reduced downtime are essential.

Typical Applications

Polywedge Screen Panels are extensively used in:

• Coal washing and coal beneficiation plants
• Dense medium recovery (DMR) systems
• Fine coal and mineral dewatering
• Iron ore processing plants
• Gold ore beneficiation circuits
• Slurry screening operations
• Sand and aggregate dewatering systems
• Mineral processing and classification plants
• Tailings dewatering applications
• High moisture material screening

Their precision slot apertures provide superior drainage capabilities while maintaining excellent separation efficiency for fine particles.

Key Advantages

High Open Area & Maximum Drainage Efficiency

The stainless steel wedge wire profile significantly increases the open screening area compared with traditional perforated or woven media. This improves water removal rates and increases screening capacity.

Superior Wear Resistance

Heavy-duty polyurethane framing absorbs impact loads and protects the wedge wire assembly from premature failure, making Polywedge media highly suitable for abrasive mineral applications.

Non-Blinding & Non-Pegging Design

The V-shaped profile wire construction reduces material build-up and minimizes pegging problems during wet screening and dewatering operations.

Reduced Noise Levels

Polyurethane encapsulation dramatically lowers operational noise compared with conventional metallic screening media.

Modular & Easy Installation

Polywedge panels are available in multiple fixing systems including Pin & Sleeve, Fast-Fit, Snap-In, Rail Mounted, and Bolt-Down configurations for easy replacement and compatibility with existing screening equipment.
