Steel Material Harp Screen with Self Cleaning Feature and Minimum 3mm Aperture for Mining and Quarry

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

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 than 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 can be connected with each other using wire knots, polyurethane, rubber or transverse wires inside plastic cover.
