Page 28 of 107 ROCK products • March 2017 • 27 Experienced Flexco team members will be available to discuss the entire conveyor system and help attendees identify chal- lenges and ways to increase the efficiency and productivity of their operations. Flexco is able to address almost any conveyor challenge – from slippage and spillage, to mistracking and wear and tear, to safety and environmental concerns. Even after a belt is up and running, Flexco stays involved to ensure that its products are delivering the top-notch performance needed for maximum productivity. Flexco, Keestrack Booth C33043 Keestrack will present highly flexible solu- tions for the recycling and aggregates industry. International product experts at booth C33043 will focus on the latest technical innovations and provide expert information on the expanding Keestrack range of machines. Having earned its early but still-lasting reputation as inventor of flexible tracked scalping and screening plants, Keestrack changed in the last few years to offer a full line of mobile technologies for mineral pro- cessing. The still-growing product range of tracked crushing, classifying and material handling solutions includes today jaws, cones and impactors, a full range of scalp- ers, horizontal classifiers and drum screens and ancillary equipment as stackers or dust suppression systems. Keestrack America was founded 10 years ago, to support the expanding dealer net- work in the North American markets. The company recently opened a new facility in Dallas. Focussing on aftersales and parts activities, the new headquarters will form a crucial element of Keestrack strategy to become the leading supplier for crushing and screening contractors in the recycling and aggregates industries. Keestrack technology is not only character- ized by the high mobility between and on sites or its ease of operation – to guarantee economic efficiency and uncompromised end product quality, the company is also focussing on state-of-the-art drive technolo- gies and sophisticated processing concepts. Highlighting this integral approach at Con- Expo-Con/Agg will be the new H4 tracked cone crusher. The light and compact plant features the KT-H4 cone crusher, adapted and supplied by a world-leading cone spe- cialist. The fully automated unit produces up to 250 tph at maximum feed sizes of 7-in. The wide variety of concaves allows a high flexibility in secondary or tertiary pro- duction of highly defined end fractions. To optimize production the plant can be optionally equipped with a pre-screen with fines chute and – as a world's first – with a highly efficient three-deck secondary screen module with recycling conveyor for closed-circuit processing. A big feeder volume, large screening areas and high stockpile capacities allow very productive operations as in-line or stand-alone unit. The Keestrack H4 crusher features a hybrid diesel-electric drive concept: 345-kW diesel (Tier 4f ) / 330 kVA gen set / 135 kW E-drive for the crusher. This guarantees economic fuel consumption and ease of maintenance through the wide use of electric motors on screens and conveyors. The recently introduced full-hybrid version – H4e – even allows full electric operation through mains or an external gen set. An additional electric motor/hydro pump then supplies the hydraulic driven feeder, the secondary screen module, the tracks and all hydraulic cylinders. Keestrack will also display the tracked impactor R3, at 33 tons the smallest unit of its impactor range; and the 55-ton R5. Both machines feature active pre-screening and will be shown with full optional equipment, which includes magnetic separators, fines conveyors and secondary screen modules with closed-circuit operation. Keestrack,
