Key features

  • Move material smoothly without bridging, thanks to a tall, wide throat opening.
  • Extend belt life even under tough loading conditions with closely set, heavy-duty rollers supporting the apron conveyor.
  • Keep screen weights low when processing wet materials by clamping on a smaller diameter tension screen wire and increasing screening area.
  • Speed up your clean up because the flashing and sheeting fit tightly against the drum and conveyors to reduce spillage.
  • The revamped TR521 with wireless remote control offers intelligence to the machine for operational setting control and allows the operator to monitor from a loader cab or distant location.
