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.
|Profile Wire Width||Relief Angle||Typical Support Rod|
|1/16” (.063”)||13 degrees||Small round rod|
|3/32” (.093”)||13 degrees||Round or Rectangular bar|
|1/8” (.125”)||13 or 5 degrees||Round or Rectangular bar|
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.
