Keestrack R3 and R% impact crushers
The R3 model from Keestrack is said to offer high crushing efficiency
Keestrack is unveiling its latest R3 and R5 tracked impact crushers. The R3 weighs in at 33tonnes while the R5 is a 55tonne machine. Both share technical features and feature active pre-screening, while they are available with optional equipment that includes magnetic separators, fines conveyors and secondary screen modules with closed-circuit operation. The units have direct driven crushing units with large and heavy rotors, delivering high crushing energy combined with smooth running. Large inlet openings and efficient overload protection systems are said to ensure productive operation in typical recycling applications without cost-intensive pre-sorting or pulverising. The machines are offered with diesel-hydraulic drives with modern load sensing hydraulics. The R5 can also be equipped with a hybrid diesel-electric drive: A 150kVA on-board gen set then supplies the electric drives for conveyors and screen modules, offering important fuel saving potentials up to 25% compared to the diesel-hydraulic version.
