Wedge Wire type 120 degree curved wire screen plate

Wedge Wire type 120 degree curved wire screen plate consist of a concave curved profile wire screen mounted in a frame with the screen openings perpendicular to the flow, also referred to as DSM Screens. Wire screen plate is well suited for high capacity filtration, which a curved screen has greater capacity than a flat screen due to forces exerted as material flows against the curved surface.

Simplified in design, the way these screens work is by the unwanted material flowing over the inclined screen surface. A layer of unwanted material builds up and slides down into a bin or waste basket. Sieve bend screens are mainly used in dewatering, applications that require liquid / solid separation.

Application of Wedge Wire type 120 degree curved wire screen plate

Some of these industries include coal mining & quarrying, sugar & mineral processing, pulp & paper, cement manufacturing, fruit and vegetable wastewater processing etc.

How it works of Wedge Wire type 120 degree curved wire screen plate

Solids-bearing liquid (slurry) is poured into the feed box and overflows onto the screen. The sharp, leading edge of each wedge wire slices away a thin layer of water and small particle solids. Larger particles continue down the screen surface until most of the liquid is removed. The size of particles is determined by the size of the coal particles and their settling velocity in the liquid. Separation size, in most operations, is usually about half the size of the screen opening.
