Non-blinding screening products offer many effective solutions to difficult sizing and aggregate separation conditions that are usually associated with efficient screening and accurately sized salable aggregate. Specifically, these include fine material “blinding” and near size material “plugging/pegging” conditions. These troublesome screening situations exist in numerous aggregate processing facilities and usually present “bottlenecks” where efficient aggregate flow and accurately sized material is imperative. Efficient screening is but one of the necessary ingredients of cost-effective aggregate processing, although it is usually the most important.
Applying the correct self-cleaning screen, based on your particular screening application, can make a significant improvement in the profitability of your screening operation. Hoyt Wire Cloth considers this to be our highest priority and eagerly seeks cost-effective and long-lasting solutions to your most difficult screening problems.
Type D
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.
Type H
The H mesh of self cleaning screen mesh is made of several horizonal and parallel crimped wires. It looks like the herringbone pattern, which can offer better sizing control than Type D mesh and W mesh by eliminating more flats and elongates.
Type S
Specifically designed to eliminate the blinding and plugging conditions associated with screening blind-prone and plug-prone aggregate and other difficult-to-screen material.
