Screen Services' StaticArc sieve bend screening unit is the answer to many de-watering, sizing, and wastewater cleanup problems. Typical uses are sewage treatment, laundry wash water clean-up, poultry, fish, fruit and vegetable wastewater processing, minerals processing, coal preparation, paper production, textile plants, and many more. 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.
Sieve bends are also known as DSM screens, after Dutch State Mines, who introduced the sieve bend as a static sizing screen having ten times greater capacity than conventional vibrating screens.
As slurry flows down the screen each wedgewire's sharp leading edge slices away a thin layer of water and small-particle solids. Larger particles continue down the screen surface, with much of the liquid removed. Separation size is considerably smaller than screen openings, usually about one half the opening size.
Low Headroom - only 1.1 metres (44") tall for the 900 mm 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 0.2 mm (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.
Flexible Design - we can supply units with any features you may require.
