Partially Welded Tufflex
The Tufflex screens, particularly those that are only partially welded and which give off a secondary vibration effect, have the capacity to self-clean, providing the site with the capacity to run all year round. Thus, the cost of the replacement screen isn’t the only metric to measure; this site has had a 35 to 40 per cent improvement in production capacity, allowing it to service customers throughout the year.
The Tufflex screening range is available with either square or rectangular apertures of varying sizes. The screens are either welded on every junction, or partially welded at every second intersection. The polyurethane coating provides extended wear life when compared with traditional wire screens, which become worn as aggregate and rocks are compounded over them. The composition of the polyurethane provides some slip for the product to be screened effectively while causing minimal damage to the screening substrate. Depending on the product being screened and the surrounding regional climate, HUATAO Group’s extractive team can assist in the selection of the most appropriate Tufflex combination.
OHS is not potentially the first criteria when selecting a screen type but as we all continue to focus on improving the safety of our employees, customer and contractors, the OHS elements of any choice are increasingly important. Tufflex screens are far lighter than their traditional woven wire counterparts. They are usually supply rolled and can be manoeuvred by one person, in sharp contrast to traditional woven wire, which necessitates a forklift, pallet or even boom lift to be lifted on-site. OHS practices may require three points of contact, and therefore moving screens using more than one person, but this task is even safer and easier given the reduced weight of Tufflex.
Cuts and abrasions normally associated with traditional screening media are all but negated; there are no sharp edges caused by cut wires along the edges of screens. Tufflex screens are fully encased in polyurethane, with only the hooks outstanding.
