Mainly used for liquid/solid separation.
Sieve Bend Screens have another name as DSM sreens because the Dutch State adapts sieve bend in mine development first. Sieve bends are manufactured to suit a wide range of 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.

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.

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.
Sieve Bend Features:
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.
