MAIN ADVANTAGES

  • Closed-Circuit System – Crusher and Screener in One: The biggest advantage of this Keestrack R3e is the rear-mounted 4.34 m² single-deck screener with a recirculation system. This means that the crushed material is immediately screened. The correctly sized fraction is directed to the final conveyor, while the oversized material is returned to the crusher for re-crushing. You get a calibrated final product without any additional screening plant, thus saving time, fuel, and logistics costs.

  • Efficiency and Product Quality: The vibrating feeder with an integrated pre-screen separates the fine fraction before it even enters the crusher chamber. This reduces the wear on the rotor and increases overall throughput. The Ferrit magnet effectively separates metal contaminants, making the machine ideal for concrete recycling. A frequency converter allows for rotor speed adjustment, adapting the crushing process to different materials and producing the best-shaped end product.

  • Modern Control and Maintenance: The PLC control system with a large 7-inch LCD screen provides full control over the machine’s parameters. The remote control allows the operator to safely control the tracked undercarriage and material feed from a distance. The central greasing system automates daily maintenance, saves time, and ensures a longer component lifespan.
