38 • ROCKproducts • June 2019 Polydeck Polydex is the company's line of modu- lar polyurethane screen panel solutions. A good choice for many screening cir- cuits, Polydex panels are especially well suited for wet applications. Panels are also available in formulations to address applications involving high microbial attack (Polydex Florida mate- rial) and sticky material (Polydex low durometer polyurethane). Polyurethane offers the most options, not only in terms of screen openings, but also in the integration of perfor- mance enhancing features like dams, restricted flow bars, skid bars and deflectors. Polydex options are numer- ous, and are available for issues like high wear zones, pegging, bed depth creation, drainage rates and high open area. Ease of use of the company's Poly- urethane media is a significant benefit for maintenance crews. All polyurethane injection-molded panels offer many inherent benefits such as superior quality, faster pro- duction rates, better dimensional consistency and with Polydeck's inter- nal tooling capabilities, new features or changes can be made quickly. Sur- face features are also injection molded into place, ensuring that they are uni- form and stable parts of the screen media itself. If you're currently using some type of steel screen media, you know how much noise your screening operation makes. Polyurethane and rubber screen media can reduce that noise level by as much as 9 decibels. That's a 50% reduction as perceived by the human ear. That means plant personnel can work nearby for longer periods with- out damaging their hearing. And, if you have neighbors, think how happy less noise will make them. Polydeck, Superior Industries Superior's Anthem Inclined Screen includes a number of distinguishing features that set it apart from compet- itor models. • The Anthem Inclined Screen fea- tures bottle jack-lifting points that simplify your spring replacement. The lifting points for changing out springs are in each of the four cor- ners of the screen, a design exclusive to Superior. This allows you to simply put a bottle jack in and raise up, requiring only six to eight bolts to remove and slide out the old springs. This maintenance convenience elim- inates the need for a crane or bucket loader, allowing you to replace the springs quickly and safely. • A fully enclosed, segmented belt guard offers safer operation and easier access for maintenance. Belt guards are typically very large and heavy, making them difficult to replace alone or without the aid of heavy machinery. The belt guard is segmented into five pieces with no piece being heavier than 50 lb. This segmentation speeds up your replacement process. • Hinged access doors prevent material spillage by sealing access holes and the hinges ensure the doors are never misplaced Backed by the industry's first two-year standard warranty, the Anthem Inclined Screen is available as a stand-alone unit or configured on a screening plant. Superior Industries, www.superi- Weir Weir's Enduron and Trio range of screening equipment are suited to a wide range of applications and deliver outstanding performance and reliability. Combined with its extensive range of screen media, Weir offers comprehen- sive screening solutions. Its extensive knowledge and commitment to the research and development of screening technology and wear performance com- pounds ensures that its products are built to last, according to the company. Also, its Snapdeck Classic is the flagship screen media system offered by Lina- tex in a variety of applications ranging from dewatering screens to heavy duty aggressive applications. The pinless rail system is sturdy and secure in any application, and also works well on curved surfaces (e.g. sieve screens, trommels). Panels are the same for both side and center installation on a screen deck, and application-specific surface features can be molded in as required. U-channel stringers are avail- able in both steel and urethane, both reinforced and non-reinforced. Weir, S Screening
