Keestrack ’ s new light and compact H4 tracked cone crusher features a hybrid diesel-electric drive concept for fuel efficiency and ease of maintenance .
Belgium based Keestrack will be presenting its latest products for contractors in the recycling and aggregate industries at this year ’ s CONEXPO-CON / AGG show in Las Vegas .
On show will be the new light and compact H4 tracked cone crusher , featuring the KT-H4 cone crusher , which has an 8m 3 hopper and 250 tonnes per hour processing capacity at maximum feed sizes of 185mm . The crusher can be used in primary , secondary , tertiary , or quarternary crushing .
The plant can be optionally equipped with a pre-screen with fines chute and a highly efficient three-deck secondary screen module with a recycling conveyor for closed circuit processing . The effective screen area is 5.4m ² on each deck , with return conveyor . A big feeder volume , large screening areas , and a high stockpile capacity enable productive operations for both in-line and stand-alone units .
The machine features a hybrid diesel-electric drive concept (( 345kW Diesel ( Tier 4f ) / 330kVA Genset / 135kW E-drive for crusher )) for fuel efficiency and ease of maintenance . An additional electric motor / hydro pump powers the hydraulic-driven feeder , secondary screen module , tracks , and all hydraulic cylinders . The full-hybrid H4e version allows full electric operation through mains or an external gen set .
Keestrack will also be displaying the 33-tonne R3 tracked impactor , the smallest unit in 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 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 .
The direct-driven impact crushers are equipped with large , heavy rotors to deliver high crushing performance and smooth running . Both units include large inlet openings and efficient overload protection systems to ensure productive operation in typical recycling applications , without costintensive pre-sorting or pulverising .
