This wide range of Wedge wire screen panels, cylinders, baskets & sieve bends with slot widths from 50 microns and tubes from 25mm dia for filtering and separation purposes can be supplied in many material types.
Typical uses cover – dewatering, draining, separation and extraction in many process industries, where high throughput is required, whether its dewatering, screening, filtering, drying of product of abrasive or corrosive properties
They are either fabricated in flat panels with V-sectioned profiled wire arranged in a parallel form and resistance welded to a number of support cross rods or by winding a continuous V-sectioned extruded wire helicoidally onto support bars in the form of a cylinder and welded at each intersection.
The composition of wires and supports can be of different shapes, sizes and materials for different applications where temperature, pressure and applicable conditions prevail such as abrasion and corrosion.
One of the important features of wedge wire screen for filtering and separation is the continuous aperture or “slot”, which automatically provides a large open area guaranteeing a very low pressure drop through the filtering surface with a low tendency to blind or clog.
“Slot widths” are very precise, but more so with looped wedge wire. This type being used for starch screens for the extraction of cornstarch
Due to the wires being wound close together and the large number of welds, wedge wire screens are inherently strong and able to provide extended life in such areas as industrial waste treatment.
The continuous aperture and triangular wire section ensures there are only two particle contact points, which minimizes the risk of blinding and clogging.
Segmental wedge wire screen floors can be designed for individual requirements in terms of finish, number of segments and diameters for the needs of the brewing and sugar industry.
The following are a few of the types of screen available designed against special characteristics.
