Overview

The TR521 Tier 4F Stage IV trommel screen is specifically designed to separate by size a wide variety of materials such as compost, soil, sands, gravel, light aggregate and sludge. Screen enhancements to the drum enable quicker and simpler changeout and tensioned screens allow for increased overall open screen area. 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.

Features and Benefits

  • 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.
  • See your Vermeer dealer for comprehensive service and genuine Vermeer replacement parts.
