Advantages : Wedge Wire Screens provide a unique combination of the most important features required for maximum screening efficiency –

  • Free Clearance : The wedge-shaped sections of the wire from aperatures that become progressively wider in a downward direction, thus ensuring rapid flow of material through them. Clogged and blinded aperatures are reduced to an absolute minium.
  • Lateral Strength : In our opinion no form of screening surface witl i apertures as fine as those of wedge wire screens, can compare with the mechanical strength and working efficiency of wedge wire.
  • Percentage Open Area : For a given aperature size, wedge wire screens have a much larger percentage of open area than conventinal sieves.
  • Wearing Life : Owing to a greater wearing area being provided by hat top surfaces, wedge wire screens retain their aperature for a longer duration than round wire screens.
  • Some other advantages of Looped type of wedge wire screens over other type of screens are :
    • Self Supporting High Abrasition resistance Low pressure drop High resistance to Vibration
    • Looped Wedge Wire Screen construction is particularly recommended when high Vibration resistance and fine accurate aperture are needed.

Types Of  Screens :

  • Flat Panels
  • Curved Screens / Sieve Bends & Cylinders
  • Centrifuge Baskets
  • Rotary Wedge Wire Screens
  • Run Down Screens
  • Wedge Wire Slot tubes
  • Filter Nozzle Screens

Industrial Applications : Wedge wires can be employed in almost all industrial processes which require very fine and uniformly accurate aperture, combining rapid discharge of material and high mechanical strength. Some of the specialized applications of these screens are given below –
Wedge wire screen used in industries for water, oil filtration equipments like


Also Used In :

  • Coal and Coke Washeries : Flat and curved wedge wire screens and Centrifuge Baskets with suitable re-inforcements are used for dewatering processes on stationary and moving frames, suction filters and centrifugal driers.
  • Ore Beneficiant Plants : In Iron and other Ore benificiant plants, wedge wire flat screens, Curved screens and Centrifuge baskets of fine and very fine aperture are used for efficient Dewatering and recovery of fines.
  • Sugar Mills : Flat, curved and cylindrical wedge wire screens are used for Juice Filtration and Bagasse Separation drainage in tanks in conjunction with scraper conveyors as well as for draining crushed sugar cane supply in D.S.M. Screens.
  • Cement, Chemical and Fertilizer Plants : Flat panels, Curved wedge wire screens, Cylinders and Centrifuge baskets with cylindrical type, conical type and pusher type have many and varied applications in these industries.
  • Cellulose, Wood and Straw Pulp and Board Industries : Wedge Wire cylinders, Flat panels and Centrifuge baskets are used for preliminary screening for knot catchers and for efficient fibre recovery Wedge wire screens ensure greater efficiency than the conventional perforated or machined slotted plates.
  •  Sewage, Effluent and Water Treatment : Flat wedge wire decking in final settlement tanks provides tertiary treatment for the reduction of suspended solids. It is also the medium used in a technique for the consolidation of sludges where the rate of filtration is controlled at low operating pressures. Sewage, aluminium hydroxide, iron hydroxide and other industrial sludges are being successfully dewatered on wedge wire.

Static Sieve-bend screen for food processing

Static Sieve-bend Screen, Wedge wire screen


The static filter screen retains the solids on the surface of the screen from where they are removed by the movement down the slope of the screen. The filtered liquid falls through the screen and creates a self-cleaning effect. The solids are thrown out by the gliding down the slope and can be collected in a stainless-steel drain container.

Our bend screen is the solution to many de-watering,sizing,and wastewater cleanup problems. Typical uses are sewage treatment, laundry wash water clean-up, poultry, fish, fruit and vegetable wastewater processing, minerals processing, coal preparation, paper production, textile plants, and many more.

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.

Sieve Bend Screen 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 0.02 mm (0.0008″).
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 also make manufacture according to your detail specifications and we assure that we will give you the best services.

Flat Panels & Curved Screens

Wedge wire panels have a high open area and continuous slot openings. wedge wire screen consists of a v-shapped 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.This makes the screen self-cleaning by allowing “near slot size” particles to pass through the screen rather than plug the opening. And the products are made by continuously winding a wrap wire onto a frame of support rods.
