New crushing and screening equipment from Keestrack
Belgian manufacturer to showcase recycling expertise at Conexpo-Con/Agg 2017
KEESTRACK, global specialists in mobile crushing and screening equipment, will be attending this year’s Conexpo-Con/Agg show, in Las Vegas, to present their latest products for contractors in the recycling and aggregates industries.
Among the mobile equipment on show will be the new light and compact KT-H4 cone crusher, which has a 250 tonnes/h processing capacity and a wide variety of concaves to allow high flexibility in secondary or tertiary production of highly defined end fractions.
To optimize productivity, the plant can be optionally equipped with a pre-screen with a fines chute and, according to Keestrack, as an industry first; a highly efficient three-deck secondary screen module with a recycling conveyor for closed circuit processing. In addition, a big feeder volume, large screening areas and a high stockpile capacity will allow productive operations in both in-line or as a stand-alone unit.
The machine features a hybrid diesel-electric drive concept (345kW) that delivers fuel-efficiency and ease of maintenance, thanks to the wide use of electric motors on screens and conveyors. An additional electric motor/hydro pump also powers the hydraulic-driven feeder, secondary screen module, tracks and all hydraulic cylinders.
Keestrack will also be displaying their 33-tonne R3 tracked impactor, the smallest unit within the company’s impact crusher range, and the 55-tonne R5 model. Both machines feature active pre-screening with optional equipment, including: magnetic separators; fines conveyors and secondary screen modules with closed-circuit operation.
The direct-driven impact crushers are equipped with large and heavy rotors to deliver high crushing performance combined with smooth running. According to Keestrack, both units include large inlet openings and efficient overload protection systems to ensure productive operation in typical recycling applications without cost-intensive pre-sorting or pulverizing.
The machines are powered by diesel-hydraulic drives with modern load sensing hydraulics, although the R5 model can be equipped with the optional hybrid diesel-electric drive, which offers fuel savings of up to 25% compared with the diesel-hydraulic version.
