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.
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 Tufflex Screen 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.
