Wedge Wire Screen Working Principle, Categories and Advantages

 Wedge wire 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.

 

Advantages

（1）Its uniform filter slots and high precision ensure the effective retention of filter medium.

（2）Wedge wire screen has a larger circulation area compared with other screens.

（3）The tiny gaps between wedge wires form a smooth wedge-shaped cross section, which makes sure no dead ends, excellent resistance to block and easy to backwash (blow wash).

（4）It has high mechanical strength and can withstand high pressure drop.

performances and can totally adapt to various harsh environment

（5）It adapts to different forms of fluid direction with high strength, large flow and high pressure resistance performance.

（6）It maintains stable filtration accuracy and can be reused repeatedly and work reliably.
