54 • ROCK products • May 2018 www.rockproducts.com EQUIPMENT & TECHNOLOGY SCREENING & SIZING German screening manufacturer Spaleck offers "Evolution," a high-end screening machine that makes the screening of the most diverse types of materials easier and more flexible than ever before, according to the company. The Evolution is perfect for screening and processing pre-shredded materials. It can be used to produce up to four different screening fractions with just one machine – even in extreme outdoor conditions. "The Evolution is equipped with additional innovative features from Spaleck, making it the ideal solution for the demands placed on modern screening technologies today," said Frederik Stening, head of applica- tion engineering at Spaleck. The extremely efficient SmartSUSPENSION air spring system is a radical new development here. The new technology reduces vibration levels to an absolute minimum and elimi- nates the need for an additional isolation frame. "SmartSUSPENSION isolates vibrations much more effec- tively than standard air spring systems – up to 99 percent in fact," Stening said. The new FineSideCOVER side panel seal was also developed with current customer requirements in mind. FineSide- COVER is the first system that allows users to replace the end component of their Flip-Flow screen easily and flexibly. "They can switch quickly and easily between a trough-shaped end for optimal screening material and a flat end for better screening performance," said Stening. The system is not only flexible and efficient; it also keeps dirt out of the side bol- sters, which minimizes the amount of cleaning that needs to be done. The LubricationCONTROL unit rounds out the range of Evo- lution features. The automated central lubrication device ensures optimal lubrication at all times. This not only minimizes the risk of bearing damage but also reduces main- tenance and service costs. Spaleck, www.spaleck.de Sandvik Debuts New QE241 Scalper Ideal for smaller end users where performance, 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 sharing common characteristics from its larger siblings including a two-way split configuration option and sequential 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 1,240-mm dou- ble-deck screenbox. This offers the largest scalping area in its class, which combined with the banana-type bottom deck arrangement, will provide a highly effective and efficient screening solution like no other. The 1,200-mm/47-in. 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 config- ured 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 paramount importance for our operators," Sandvik said. "A key benefit to our cus- tomers is the easy-to-use control system and user interface with sequential start, a common feature across our 1 Series screens and scalpers. The model also comes with two speed tracking which helps to reduce travel time between jobsites." Designed for ease of transport, the 17,500 kg/38,580 lb. 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 com- pact 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 ser- vice and screen media changes. Sandvik, www.sandvik.com Spaleck Offers All-Purpose High-End Machine
