Progress Eco Pro-Slot - Flat Panels of Wedge Wire Screens
Flat panels of wedge wire screens are manufactured by welding special profiled working wires to support wires at an angle of 90 degrees. A precise slot is received by means of applying modern welding technology between working wires and support wires. The result is a rigid screen construction with the capability of withstanding heavy loads.
Innovative solutions of technology allows:
- to control quality of welding
- to use various working wires
- to design various slot sizes in one screen
- to design various support wires in one screen and
- various distances between support wires in one screen
- to gain superior flatness of sieves (no corrugation of working wires between support wires)
- Slot: from 0,05 mm
- Maximum size: 3500 x 4000 mm
- Profile tilt: 0°-10°

* Different set of tolerances needs individual agreement
An important parameter of the screen is the open area. Open area Fo(%) is the relation of the slot surface to the total screen
surface. Open area is calculated according to the following formula:
F0 = S/(S+A) x 100 (%)
A– width of the working wire ( according to the table of working wires)
S – slot size
For example:
A sieve was made of working wire Sb 28 with slot s = 0,24 mm
F0 = 0,24/(0,24+2,2) x 100% = 9,6%
