TR521 Trommel Screen

Trommel Screen | Vermeer TR521

Designed for topsoil with high moisture content, the TR521 is outfitted with a 5’/1.50 m drum and a hopper that holds 5 cubic yards/3.82 cubic meters. The 65’/19.81 m conveyor helps process wet material with consistent results. Access the drum through removable side panels, drum end or top of the drum. Get the day’s job done with the 521’s powerful and efficient 99 hp/73.8 kw John Deere 5030HF Tier 3.


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.
