50 • ROCK products • January 2019 EQUIPMENT & TECHNOLOGY SCREENING & SIZING Haver & Boecker's Tyler F-Class por- table plant offers increased mobility to maximize flexibility and ROI for aggregate and mining operations. Each portable plant features the F-Class vibrating screen mounted to a cus- tom-built chassis. The portable plant includes a hydraulic system that raises the vibrating screen to its inclined oper- ating position. These two features allow producers to move and set up the por- table F-Class in less than 30 minutes in nearly any location. "With the fast pace of the industry and the underlying need to increase screening efficiency and profitability, it was the right time to launch the por- table F-Class," said Karen Thompson, Haver & Boecker Canada president. "We're using our decades of experience to develop the absolute best mobile screening platform for our customers." Beyond flexibility, Haver & Boecker's F-Class portable plant offers as many as three screen decks. The vibrating screen features an advanced double eccentric shaft design, supported by four high-performance, double-spher- ical roller bearings. The F-Class is ideal for screening situations that require consistent, load independent perfor- mance at constant g-force. Featuring a unique and reliable, proven four-bear- ing technology, the vibrating screen delivers a consistent stroke, which two-bearing screens cannot provide. With the right media choice, the F-Class virtually eliminates blinding, pegging and material contamination. The vibrating screen is mounted on a portable chassis, which uses hydrau- lics to lift the screen to the operational angle for each application – usually 20 degrees. Producers use the included six hydraulic running jacks to lift the chassis into position. The jacks level the chassis from side to side and front to back and allow producers to operate the vibrating screen without adding blocking below the chassis for support. This setup process takes less than 30 minutes to complete. Take down is even faster, requiring less than 20 minutes to lower the unit so it can move to the next location. Haver & Boecker offers the Pulse vibra- tion analysis program to monitor the ongoing health of vibrating screens through real-time views, logged reports and data analysis. It's designed by Haver specifically for vibrating screens to catch small inconsistencies before they grow into problems and downtime. Haver & Boecker, Sandvik QE241 Scalper Versatile, Mobile Ideal for smaller end users where per- formance, versatility, transportation and setup times are most important, the QE241 scalper also benefits from Sandvik's long history of mobile scalper development as well as shar- ing common characteristics from its larger siblings including a two way split configuration option and sequen- tial start-up. Capable of scalping before or after a small crusher, the QE241 features a heavy duty variable speed belt feeder and a highly aggressive 11- x 4-ft. (3,500- x 1240-mm) double-deck screenbox. This offers the largest scalping area in its class, which com- bined with the banana-type bottom deck arrangement, will provide a highly effective and efficient screen- ing solution like no other. The 47-in. (1,200-mm) wide conveyor can handle the toughest oversize material and two hydraulically folding side conveyors handle the fines and midsize products. With a wide choice of screen media available, the QE241 offers customers a highly versatile unit that can be con- figured to suit the specific requirements of the application. Its robust chassis has been designed to be compatible for two-way or three-way split versions, a unique feature in this product category. "The safety and comfort of use is of par- amount importance for our operators," the company said. "A key benefit to our customers is the easy-to-use control system and user interface with sequen- tial start, a common feature across our 1 Series screens and scalpers. The model also comes with two speed track- ing, which helps to reduce travel time between jobsites. " Designed for ease of transport, the 38,580-lb. (17,500 kg) model comes complete with hydraulically folding tail and side conveyors, together with a rigid one-piece hopper for quick set-up times. These features, combined with its compact footprint, make it ideal for contractors requiring the need to travel quickly from site to site. Ease of maintenance is ensured through the hydraulic jack up facility on the screen box, also common with its larger siblings. This allows easy access to the bottom deck for service and screen media changes. Sandvik, Haver & Boecker Brings Flexibility to Jobsites with Tyler F-Class Portable Plant
