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
