36 • ROCK products • September 2015 www.rockproducts.com EQUIPMENT & TECHNOLOGY SCREENING & SIZING W eir Minerals North America announced that the Durex wire screen media product line is celebrating its Gold- en Anniversary in 2015. The Durex product facility, based in Luck, Wis., is proud of the reputation it has earned during the past half-century of successfully meeting and exceeding cus- tomer needs in the aggregates and mining industries. To commemorate the achievement, Weir Minerals is launch- ing the 50-50-50 Anniversary Appreciation Program. The 50-year celebration offer includes 50 percent off one full deck of any Durex wire screen media product. Customers have 50 days to benefit from the promotion – Aug. 17 to Oct. 5. Durex Products, Inc. was founded in 1965 by R.D. Scarlett, a former Fortune 500 company executive and civil engineer. In an already competitive aggregate screening market, where woven wire screen cloth was viewed as merely a commodity, Scarlett saw an opportunity to successfully apply innovative product development with superior customer service . The company initially offered woven wire screens out of its facility in Luck, Wis., and quickly gained market share by aggressively serving the needs of sand and gravel, and crushed stone customers in Wisconsin and Minnesota with prompt delivery, quality products and a willingness to help producers solve difficult screening challenges. In the early 1970s, Durex Products expanded farther into the midwest, north atlantic and southeastern U.S. During the mid-1970s, as new technology was developed in the man- ufacture of longer lasting screens, Durex Products saw the potential of synthetic screen media to increase wear life and reduce maintenance costs. The company expanded its pro- duction line to include polyurethane screen media. Over the following decade, it became apparent that not all screening challenges could be solved with wire cloth or poly- urethane screen surfaces. In 1986, the company added a rub- ber screen manufacturing line. By the early 1990s, with its full line of woven wire, vulcanized rubber and molded polyurethane screens, Durex Products was positioned to provide extremely cost-effective, produc- tion-enhancing solutions for its customers in North America. During the past 50 years, and even as Durex Products subsequently became a part of the Weir Minerals lineup, the brand continued to maintain a reputation for product innovation. Rubber and molded polyurethane screens and wear products subsequently became marketed under the Linatex brand, which is transitioning to a new state-of-the- art R&D; and manufacturing facility in Salt Lake City. The Durex and Linatex brands from Weir Minerals provide a full offering of screen media products with a legacy of engi- neering excellence. • Standard woven wire: Made from tempered, stainless or high carbon steel, the durability and strength of Durex woven wire permits use of lighter gauge wire, offering more openings per square foot of screening area. Longer life means less downtime and lower operating costs per ton of material. • Livewire screen media: Designed to boost production by reducing costly, time-consuming blinding, plugging and pegging problems – while also delivering superior wear life. Livewire screen media is available in diamond-shaped, alternating "Z" and straight wire, herringbone and straight wire slot openings for maximum output in a variety of dry or damp applications. Its 60-durometer rubber strips pro- vide superior flexing action. • Accuslot wire screen: Especially effective in processing crushed stone, sand and gravel, and materials with high moisture content. Accuslot screens deliver the high pro- duction capability of a slotted screen, with sizing accura- cy approaching that of a square opening, minimizing the passing of slivers and chips and greatly reducing plugging and blinding. • Vibraspan screen media: The highest throughput of any wire screen from Weir Minerals, built for long life, easy installation and high production. Vibraspan screen media is an end-ten- sioned, inter-crimp or straight wire specialty long-slot wire that is manufactured to precisely match each machine's sup- port bars for maximum screen life and open area. • Armor screen: A combination of premium wire cloth with molded polyurethane coating. Armor screens are designed to provide a higher open area than conventional polyure- thane screens and far longer wear life than conventional wire cloth screens that are used in medium load applica- tions with highly abrasive wear. Armor screens are also designed to provide high throughput, reduced plugging and reduced noise. Weir Minerals, www.weirminerals.com Weir Minerals Celebrates Durex Golden Anniversary
