Industrial Sieve Bend Screens (DSM Screens)
High-performance curved wedge wire screens for gravity-fed sizing, dewatering, and solid-liquid separation.
What is a Sieve Bend Screen?
The Sieve Bend Screen (also known as a DSM screen) is a curved static screen used for separating solids from liquids. It is composed of a curved wedge wire screen panel mounted in a frame with openings perpendicular to the flow. Compared to flat screens, sieve bends have a higher capacity and efficiency due to the gravitational force and the curved profile.
- Materials: Grade 304, 316, 316L Stainless Steel.
- Screen Type: V-shaped profile wire (Wedge Wire).
- Operation: Static (No moving parts).
Advanced Features
Self-Cleaning
The V-shaped wire design prevents clogging and ensures continuous flow.
High Capacity
Significantly higher throughput than flat vibrating screens of the same size.
Zero Maintenance
No moving parts means no power consumption and minimal wear.
Applications
Mineral Processing
Coal, iron ore, and copper tailings dewatering.
Food & Starch
Starch extraction, fruit juice fiber removal.
Wastewater Treatment
Primary solid removal in municipal and industrial plants.

Why Choose Our Wedge Wire?
Our Sieve Bend Screens feature precision-welded V-profile wires. Each intersection is resistance-welded to ensure structural integrity. The sharp leading edge of the wedge wire slices the liquid film, effectively drawing the liquid through the slots while directing solids over the screen face.
Frequently Asked Questions
It depends on the particle size of the solids you want to remove. Usually, the slot size is twice the size of the smallest particle to be retained.
Yes, we offer standard 45°, 60°, and 120° arcs, but custom angles can be manufactured based on your flow rate requirements.
