Sieve Bend Screen, Vadodara, Gujarat, India

Structures of Sieve Bend Screen

Wedge wire sieve bends are made of stainless steel wedge wires. They are consist of a concave curved profile wire screen, which are inserted into a stainless steel frame. The wedge wire sieve bends are manufactured by wrapping and welding stainless steel V-shaped profile wire and support rods. Then the panel screens are cutting and curved into arc screen. The wedge wire sieve bends have continuous slots, which has efficient filtering performance. Forces exerted as materials flows against the curved surface, curved screen structure has better filtering and greater capacity than the wedge wire screen panel.

Working Principle of Sieve Bend Screen

DSM screen (sieve bend screen) is ideal for sizing and dewatering applications to remove solids from liquids or in solid/solid separation for dry feed situations. When the filtering materials flows against the sieve screens, Sieve bend screens can be manufactured into a variety of width, arc length and aperture to suit the flow rate and material sizing being separated. The feed materials are directed vertically and tangentially over the full width of the upper screen surface, then the material flows down the concave surface at right angles to the opening between wedge profiled wires. Wedge wire sieve bend screen has continuous slots, which supplies large open area and efficient filtering performance. Curved surface structure supplies higher flow rate, greater capacity and better filtering than wedge wire screen flat panels.

As a result, Thinner materials on the underside is deflected and passed out between the wires.
