Wedge wire screens

 

 

Wedge wire screens are produced by welding stainless wires profile (type Sb) and support profile (Type Q).

The product is used in the process of sifting, sorting, drainage, filtering...Wedge wire screens are the result of highest technology production. High precision, huge durability and smooth surface allows to use it in efficient way in mining industry (coal or stone mining), chemical or food industry (sugar mills).
Because of really wide potential application of product we propose to create wedge wire screens according to individual projects. There is a possibility to create finished product (for expample whole sorter) framed strictly according to the technical sketch.

Basic technical parameters:

  • Dimensions- up to 2000x2500 mm
    *2500 - max length of support profile (Q)

Suggested grades of profiles :
0H18N9-(1.4301), 1H18N9T -(1.4541), 1H13-(1.4006)
