Wedge wire Johnson filter screen is a metal mesh element widely used in screening, filtration, dehydration and desliming operations for sieving and filtration. It has high strength, rigidity and load carrying capacity and can be made into a variety shapes of rigid screening filters.
The wedge wire screen consists of surface profiles and support profiles. Surface profiles, usually v-shaped wires, are wrapped and welded onto support profiles. The distance between the surface profiles is controlled very accurately, as it forms the slot through which the filtrate flows. The direction of the flow is determined by the position of V-shaped wires (surface profiles) in relation to the support profiles. Wedge wires screens are either flow-out-to-in or flow-in-to-out.Features of wedge wire Johnson filter screen:
