Wedge wire FLAT Screens
KAIYUAN'S flat screens can be fabrcicated with very small wires and rods for critical fine-screening operations,or with much larger wires and rods for heavy-duty operations.
The slot size is determined according to the customer's needs and application.
Standard constructions of flat welded screens
Flat Welded Screens with dimensions other than those given below are available on request.
The designation for a Flat Welded Screen is for instance: 22S/Q35 - 70
22S = surface wire
Q35 = support wire
70 = distance between support wires in mm

(*) in most cases all pitches are possible
pitch = distance between support profiles
