Wedge Wire Screen Cylinders

Our Wedge Wire Screen Cylinders are a precision-engineered filtration component designed as a core consumable part for industrial solid-liquid separation equipment such as dewatering presses, centrifuges, and screw separators. The Wedge Wire Screen Cylinders are manufactured by resistance-welding stainless steel wires with a trapezoidal (wedge-shaped) profile onto longitudinal support rods, forming a robust cylindrical filter element with continuous V-shaped slots for high-efficiency separation.

• Materials: AISI 304 (Standard) / 316L (Enhanced corrosion resistance).
• Slot Aperture Range: 0.05mm to 3.0mm (Standard production tolerance: ±0.025mm for slots ≤ 0.5mm; ±5% for slots > 0.5mm).
• Wire Profile: V-slot design, with a typical surface width 1.5 to 3 times greater than the nominal slot size at the filtration point.
• Cylinder Dimensions: Custom-built to fit OEM models. Common outer diameters range from 150mm to 800mm, with lengths up to 3000mm.
• Temperature Resistance: AISI 304 maintains mechanical properties up to 800°C in continuous service.
• Connection Types: Flanged ends, threaded fittings, or as per technical drawings.

• Documented High Flow Rate & Anti-Blinding: The V-slot geometry increases open area by 15-25% compared to perforated plates of equivalent aperture. The design prevents particle lodging; in manure dewatering applications, this reduces backpressure and maintains flow, allowing for up to 30% longer operational cycles between cleaning interventions compared to square-mesh screens.
• Quantified Strength for Pressing Applications: The welded monobloc construction provides structural integrity under radial pressure. Standard cylinders with 1.0mm slots and a 300mm diameter withstand continuous radial compressive forces exceeding 0.35 MPa without slot deformation, a critical requirement in screw press operations.
• Defined Filtration Consistency: The slot aperture is fixed at every weld point, guaranteeing a consistent separation cut-point throughout the screen's life with a deviation of less than ±0.05mm from the specified size, ensuring uniform product moisture content or solid purity.
• Material-Linked Durability: Using 304/316L stainless steel provides proven resistance to corrosion from organic acids (e.g., in manure, food pulp) and chloride ions. The wear-resistant surface of the wedge wire extends service life in abrasive slurry environments by 2-3 times compared to woven wire mesh in similar duties.

This component is specifically engineered as a replacement or OEM part for:

• Agriculture: Dewatering presses for cattle/pig manure (manure squeezing screen cylinders).
• Wastewater Treatment: Screw presses, drum screens, and centrifuge baskets for sludge dewatering.
• Food Processing: Juice extraction ("T-type cages") and starch processing.
• Chemical Industry: Filter elements in separators for catalyst recovery and crystal washing.
