Self cleaning screen mesh also named anti-clogging screen mesh and Non-Pegging / Blinding Screens , which is made of high carbon steel wire, spring steel wire and stainless steel wire. It can offer effective solutions to difficult sizing and aggregate separation conditions, such as the blinding and plugging.

Self cleaning screen mesh can separating and screening the wet and moist materials. It is widely used in the separating materials in the mining, quarry and other industries.

Depending on the placement of the wavy wires and their connection type we can divide harp screens Into following categories:

Progress Harp Type K

This type of screens is made of round wavy, wires, curved in the horizontal working plain. 

Angle between the arms equals 90.

Working size of W opening is created by diameter of the circle written into this opening.

Wires placed one next to another create openings similar to a square.

Working wires are buckled together with transversive wires using polyurethane, rubber or wires inside plastic cover.

Opening sizes: 1,5 – 35 mm
Ø Wire: 0,8 – 6,3 mm

Progress Harp Type T                                                                                                                                          

They are produced with wires of round diameter – straight and wavy placed alternately on

the horizontal working surface. Wave spread span equals 90 or 60 . Working size of W opening is

created by the diameter of the circle written into this opening. Straight, round wires have a slightly

larger diameter then wavy ones. This series of screens characterizes with high ability to withstand

heavy loads (owing to very well stretched straight wires)and good self-cleaning effect, obtained by

self – oscillation of wavy wires. Wires in this series of screens can be connected with each other using wire knots, polyurethane, rubber or transverse wires inside plastic cover.

Opening sizes: 1,2 – 14 mm
Ø Wire: 1 – 4 mm
