Sieve bend screens

Sieve Bend Screens also known as side hill screens, parabolic screens, rundown 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.

Product Specifications:

Sieve Bend Screens have another name as DSM screens, 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 screen due to forces exerted as material flows against the curved surface.

The dewatering capacity of a wedge wire cross flow sieve bend screen is primarily influenced by the screen width, the slot opening, and the wire size (width).

Screening efficiency and solids capacity are directly related to the length (arc length). Longer arc lengths should be considered for feed containing a high percentage of solids.
