Sieve Bend Screen
Sieve Bend Screens also known as side hill screens, parabolic screens, run down screens, gravity screens and DSM screens, can be custom designed to separate solids from liquids in various applications including food processing, pulp and paper, waste water cleanup, surface water intakes, corn wet milling, coal preparation, and gold recovery.
Sieve Bends are cross-flow screens. The profile wires are slightly tilted so that the leading edge is position higher which greatly increases the dewatering capacity.
A sieve bend consists of a concave curved profile wire screen mounted in a frame with the screen openings perpendicular to the flow. A curved screen has greater capacity than a flat wedge screen due to forces exerted as material flows against the curved surface.

Features:
- Low Headroom - only 1.1 metres (44") tall for the 900mm arc length unit.
- Energy Efficient - operates with no moving parts and with no energy input.
- Space Efficient - treats up to 122 litres per second per square metre of floor space.
- Quiet Operation - no moving parts means no mechanical or electrical vibrations.
- Accurate Sizing - can be used for sizing solid particles down to 0.2mm (0.008").
- Low Maintenance - the profile wire screen resists clogging by near-size particles, and the all-stainless steel construction ensures a long, corrosion-free installation.
- Easy Screen Replacement - a typical screen can be replaced in 10 minutes with no tools.
Wedge Wire Application: They are used in industries such as Sugar, Coal Mining & Quarrying, Mineral Processing, Cement, and Industrial & Urban Effluent Treatment etc. Sieve bend screens are also used as a pre-filter in urban & industrial waste treatment plants to improve the performance of the clarifier by drastically reducing the load. Widely used for fiber removal in Starch industry.
