High-Efficiency Wedge Wire Curved Screen (DSM Sieve Plate)

Advanced Solid-Liquid Separation for Dewatering, Desliming & Classification
The Wedge Wire Curved Screen, also known as a DSM Screen or Sieve Bend, is a high-capacity, economical solution for preliminary dewatering and mineral processing. Utilizing a concave curved profile, our screens leverage centrifugal force and gravitational flow to achieve significantly higher filtration efficiency than flat panels.
· Ultra-Precision Slots: Customizable from 20μm to 3000μm with a strict tolerance of ±5μm.
· Optimal Geometry: Available in 45°, 60°, 120°, 270°, and 300° arcs for diverse application needs.
· Non-Clogging Design: V-shaped wires allow slots to expand inwardly, ensuring zero blockage during long-term operation.
· Exceptional Durability: Fusion-welded stainless steel (SS304, 316L, SS321) construction for maximum wear and horizontal strength.
· Versatile Flow Options: Supports Standard Wound, Reverse Formed, Reverse Wrapped, and Axial flow configurations.

Product Overview

The Wedge Wire Arc Curved Screen Plate is an essential component for coal preparation plants and mineral processing facilities. By wrapping and welding V-shaped stainless steel profile wire around support rods and bending the panel into a precise curve, we create a concave screen that excels in fine particle classification and slime recovery.

This curved structure allows material to flow perpendicularly across the slots, stripping the fluid layer and achieving precise sizing. Compared to flat screens, the DSM screen provides greater capacity and better dewatering performance, especially when used in conjunction with hydrocyclones for desliming and medium removal.

Key Advantages

High Structural Strength: Vertical strength increases with profile depth, while horizontal strength is optimized to prevent lateral bending, maintaining slot precision under high material loads.
Precision Sand Control: With slots as small as 0.15mm, the screen provides superior classification, reducing pump maintenance and extending the life of downstream equipment.
Self-Cleaning V-Wire Geometry: V-shaped slots expand inwardly, allowing particles to pass through easily without clogging, maintaining high efficiency over time.
Extended Service Life: A specialized opening angle minimizes wear on the profile’s top surface, preventing rapid oversized aperture limits.
Greater Capacity: The arc structure enhances centrifugal separation, delivering better dewatering and desliming than static flat plates.

FAQ

Q: Why is a curved screen better than a flat screen for dewatering?
A: The curved structure (DSM) uses gravity and centrifugal force to “strip” the liquid layer from the solid material more effectively, allowing for higher flow rates and better separation in a smaller footprint.
A: Yes. We offer standard angles like 45°, 60°, and 120°, but we can customize the arc height and angle (up to 300°) to match your specific equipment frame.
A: We can manufacture curved screens with slots as small as 20μm (0.02mm), with a precision tolerance of ±5μm.
A: Sample provision is based on the quantity and complexity of the wedge wire required. For large industrial projects, we can provide samples to verify the slot precision and material grade.
