Wedge Wire screen cylinders / filter drum

Wedge Wire screen cylinders can be designed with slot openings and wires running radially on the outside surface of the screen cylinder (above left) or they can be 

positioned axially on the inside of the cylinder (above right) Screen cylinders are manufactured in various diameters from 1/2" pipe size to 35" diameter. 

Screen cylinders (above right) can be fabricated into larger diameters. Each intersection of wedge wire and support rod is welded for strength and durability.

Various wedge wire and support rod combinations can be used to produce the best screen design. Rotary Screens typically use wedge wire for the screening media. 

The above externally fed unit has a spiral wound wedge wire screen drum 36" OD x 120" long.

Screen Cylinders from vee shaped wire for filtration.  A  V shaped wire is spirally wound and welded on a cage of longitudinal wedge shaped or trapezoidal 

shaped rods. Each and every intersection between vee shaped wire and the wedge wire is welded automatically. This creates a continuous spiral slot. These screen tubes 

cylinders are also known as continuous vee slot tubes.
