Rotary drum screen
The Wedge wire is a welded stainless steel structure, mainly used for filtration, separation and retention media. It consists of surface part, usually V-shaped ( as drawing), that are resistance welded onto support part. The distance between the surface part is controlled veryaccurately, as it forms the slot through which the filtrate flows. In case of V-shaped surface part conical slots are created. The separation efficiency of Wedge wire screen is better than traditional Woven screen and perforated screen.
Rotary drum screen is a rotating stainless-steel wedge wire cylinder which is fed externally.
As the solids are captured on the face of the screen, they are removed by a discharge blade. The
mass influent constantly washing the screen, resulting in continuous self cleaning screen surface.
The continuous and automatic self-cleaning effect makes it possible to use higher hydraulic and
solids loading onto the screen in comparison with other types of screening equipment. Therefore,
substantial capital and operational cost are saving.
The 0.15-3.0mm of particle can be filtrated by rotary drum medium screen.
