Product Introduction
The wedge wire arc curved screen plate is an economical and practical solid-liquid separation equipment, mainly used in coal preparation plants and mineral processing plants for preliminary dewatering, desliming, medium removal, classification, and slime recovery of materials. You can also use it in conjunction with hydrocyclones to effectively classify, dewater, deslime, and remove medium from fine particles.
We also call cantilevered DSM wedge wire screens curved profile screen plates.We classify them as curved concave wedge fixed screens. We offer common DSM screen plate types in 45°, 60°, 120°, 270°, and 300°. We make wedge wire screen elbows from stainless steel wedge wire. They consist of concave curved profile wire mesh that we insert into a stainless steel frame. To manufacture wedge wire screen elbows, we wrap and weld V-shaped stainless steel profile wire around support rods, then cut the panel screen and bend it into a curved screen.Wedge wire mesh screen elbows have continuous slots and provide efficient filtration performance. The curved screen structure offers better filtration efficiency and greater capacity compared to flat wedge wire screen plates when the material flows onto the curved surface.
The filtration directions of the wedge wire arc screen plate include the following forms:
Main features and advantages of the wedge wire screen:
1) Horizontal strength Increases rapidly with the width of the profile, and must be sufficient to prevent the possibility of lateral bending of the wedge wire screen, which could result in loss of slot precision.
2) Vertical strength increases rapidly with the profile depth, and it requires a greater extent than horizontal strength.
3) It achieves better filtration: specialized manufacturing processes allow slot sizes to be as small as 0.15mm, so you can select suitable slot sizes based on the sand particle size in specific areas. This allows better control of sand, reduced pump maintenance, and extended well life.
4) Long service life When using abrasives, the top surface of the profile will wear over time, inevitably requiring an increase in aperture. When the opening angle is small, the increase is gradual; however, when the opening angle is large, the increase is rapid. The aperture quickly reaches an oversized limit, thus shortening the service life.
5) Non-clogging slots V-shaped wires allow the V-shaped slots to expand inward. Therefore, over the years, well efficiency does not decrease due to clogging.

Wedge Wire DSM Screen Application:
We mainly use curved wedge wire screens for de-watering, sizing, and wastewater purification applications. You can apply them in various fields, such as sewage treatment, laundry water purification, poultry farming, aquaculture, fruit and vegetable wastewater treatment, mineral processing, and paper-making.
