WEDGE WIRE FOR GENERAL INDUSTRY
Welded Wedge Wire and Looped Wedge Wire for Foundry, Chemical, Pharmaceutical, Paper and Pulp
LOOPED WEDGE WIRE SCREENS
The individual wedge wires are built into panels by feeding cross rods through the loops of the wires. The whole panel is clamped together and made secure, usually by riveting over the cross rod ends. The finished sieve is therefore a grille made up of cross rods supporting profiled wires with loops. The usual materials are stainless steel grade 304, 316, 430 and mild steel.
CURVED SCREENS AND CYLINDERS
In addition to flat panels, wedge wire can be readily made up into full cylinders and segments of cylinders. The screening face may lie on either the outside or the inside of the cylinder, depending on the particular application. Curved wedge wire sieve bends are used to a considerable extent in chemical plants, ore and coal mines, abattoirs, cane and sugar beet refineries, vegetable processing plants, paper and pulp factories, and almost any process industry where de-watering of slurries and separation of solids from liquids is required.
HARPSCREEN’S WELDED WEDGE WIRE SCREENS
Harpscreen are pioneers in the development of Wedge Wire Screens. In recent years a demand has grown for Wedge Wire assembled by welding, in contrast to the looped method described earlier. We have met this demand with the very latest in TIG welding technology.
Using specially developed machinery and advanced automatic welding our welded type screens offer a wide range of apertures with clear and unobstructed open area.
This latest development uses 6.35 mm diameter cross rods or up to 25 x 6 mm flat bars welded directly to the profile wires. Cross rod pitch can be varied to suit the application.
Reinforcements can be added as required providing the strongest and most cost effective Welded Wedge Wire screens on the market.
Usual materials are stainless steels in AISI grades 304 and 316. Other metals are also available.
As well as the usual flat or curved screens, Welded Wedge Wire is made into tubes and cylinders, with radial or straight slots. The screen surface can be either on the inside or the outside of the cylinder, to give flow in-to-out, or out-to-in. Usually made in stainless steel grade AISI 304, but other grades are also available.
Welded Wedge Wire is used in a huge variety of general industry applications – please call for more details.
