Description
Self-cleaning screens are a non-blinding, high quality screening surface that provides accurate screening and sizing.
Having many advantages over other screen types, self cleaning mesh gives higher production rates while eliminating the problem of Large unwanted flat
material that contaminates the finished product. We also can add some pu strips on the bars, it will be more wearproof to improve the life.
Advantage:
Anti-clogging
Anti-pegging
Increased wear life
Accurate sizing
Available to suit all types of mobile and static screens
With high quality, non-blinding screening surface the Flexi-Harp is the perfect mesh. The combination of different size wire used in manufacture means that
they vibrate at varying frequencies to produce a self-cleaning surface. Due to its flat surface (no knuckles Self-cleaning screens can use a smaller wire diameter
than woven wire for some applications. Separates flakes and slivers from finished product while greatly reducing problems like plugging and blinding.
Specification
Material : polyurethane coated wire rope
Aperture shape :square or rectangular
Aperture range : 2mm to big
Wire rope diameter range : 1.5mm to big
Description
Tufflex is polyurethane coated stainless steel wire rope screen with the same open area as woven wire and huge advantages over traditional screens.
The Tufflex screen is made up of two types of ropes welded together. The rope running from hook to hook is a wire rope with a thick polyurethane covering.
This rope, with the wire, allows the hooked edge screen to be tensioned like other hooked edge screens, with no modifications to machinery required.
The same maintenance procedures of checking the screen tension applies to Tufflex screens. The other rope is made up of a fine synthetic cord, also with thick polyurethane covering, and runs parallel to the hooked edge. For side-tensioned set-ups, this rope acts like rider bars for larger stones to slide down the deck, channelling smaller ones closer to the apertures. This increased stratification improves screening efficiency. With the end-tensioned screens, this rope can be used on top,
running in a cross-flow orientation, or positioned underneath the rope with the wire.
Features
Tufflex is a polyurethane-coated screen media that can be substituted for traditional woven wire screens with minimal adjustment to the screen deck.
Available in several combinations of both rope and wire diameter and aperture size, Tufflex offers additional customisation options via partially or fully welded screen cloths.
The smooth surface of the polyurethane prevents sticking and blinding, which is further enhanced by the flexibility offered by Tufflexs cloth construction.
The Tufflex cloths not only improved the quality but also minimised blinding, improved efficiency and have great wear. this provides the site with longer
periods between changeover and less downtime during busy screening periods.
The available range of Tufflex screens is extensive, with aperture sizes ranging from 1.5mm to 45mm and square and rectangular aperture shapes,
similar to woven wire. The wire rope diameter ranges from 1.5mm to 12mm, with custom-made rectangular slots as fine as 0.7mm wide.
The construction varies with either fully or partially welded wires.Sheets of poly can also be welded on for impact protection or enhanced abrasion
protection along the hooks.
