40 • ROCK products • September 2018 EQUIPMENT & TECHNOLOGY SCREENING & SIZING Haver & Boecker offers Ty-Max and Ty-Wire screen media, now with longer wear life proven through extensive field testing, according to the company. "Product testing is an ongoing pro- cess conducted to ensure products are not only meeting customer expecta- tions, but exceeding them," said Karen Thompson, Haver & Boecker Canada president. "Through rigorous testing in the field, we discovered these products are proving to be even more durable than originally anticipated, leading to fewer screen changeouts, less down- time and longer wear life." Ty-Max lasts seven to nine times longer than traditional woven wire cloth, while Ty-Wire stands up four to seven times longer. Each is poured open cast, allow- ing the screen media to harden when cured to resist wear and tear, offering one and a half to two times longer wear life over injection-molded products. Producers choose Ty-Max when they are looking for more wear life on their side-tensioned screen deck. Because it is side-tensioned instead of modular, it can be combined with other side-tensioned screen media on a cambered deck to create the optimal balance between wear life and open area. Ty-Max open- ings range from 3/32 - to - 4 in. Ty-Wire is a hybrid between polyure- thane and woven wire and is available with openings ranging from 1/8- to -1-5/8. The low-maintenance and light- weight qualities make Ty-Wire safer and easier to install than traditional woven wire, and it offers greater open area than polyurethane. It is available in both side-tensioned sections and mod- ular panels. Both feature a tapered opening design that releases more near-sized material, allowing the screen to self-clean. Typically, a switch from woven wire cloth, which requires a cambered deck, to a polyurethane modular product requires a deck conversion costing anywhere from $15,000 to $25,000. However, with Ty-Max and Ty-Wire, producers can switch to polyurethane or a hybrid screen media without the added expense of converting their cam- bered deck. Additionally, Haver & Boecker's cer- tified sales team works directly with aggregates and mining operations to determine the best screen media com- bination for each unique application. Ty-Max and Ty-Wire can be blended with perforated plate, rubber, woven wire or self-cleaning screens to extend wear life and improve performance of the screen media overall. For example, installing a section of Ty-Max at the feed end will help allevi- ate the additional wear that comes with the initial material impact. Ty-Wire can be used in the middle of the deck, for example, where basic screening takes place to give operators the ideal combi- nation of wear life and open area. Using woven wire or self-cleaning screens at the discharge end will provide maxi- mum open area at the end of the deck. Haver & Boecker Canada, Superior Industries Displays New Modular Wash Plant Superior Industries Inc. displayed its new modular wash plant at Hillhead 2018. Known as the Spirit Sand Plant, the flexible plant merges the manu- facturer's Helix cyclone, dewatering screen, sump tank and slurry pump into a single plant capable of sand pro- duction, fines recovery and dewatering. According to Superior, its brand new Helix cyclone is uniquely designed with a geometrically efficient inlet, which proves to boost performance and lower wear to internal components. In addi- tion, all wetted surfaces are lined with cast polyurethane for extended perfor- mance and life. For fines recovery applications, the Helix cyclone is designed and built by Superior in 12- or 16-in. models. Meanwhile, sand production models are sized 16- to 30-in. The manufacturer's dewatering screen is capable of removing all but 8 percent moisture content, meaning the sand produced is immediately sellable. It achieves this due to a deeper bed deign and urethane sidewalls, which remove moisture from the material screens at the tops and sides. These high tonnage dewatering screens process material up to 360 mtph or 400 stph. For sand production applications, Spirit sand plants are manufactured in five models with production up to 300 mtph or 330 stph from the screen. Seven ultra fines recovery models can be fed at rates from 20 to 161 mtph (22 to 177 stph). Each plant is designed to fit into standard shipping containers.
