- 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.
The TR521 by Wildcat trommel screen is specifically designed for topsoil with high moisture content, processing wet material with consistent results. Combine this with its 99-hp (73.8 kW) engine, 5`-diameter (1.5 m) drum and a 5-cu-yd (3.8 m3) hopper, and the TR521 is capable of producing up to 150 cu yd (114.7 m3) of consistent, quality material per hour.
As with our other units, the TR521 features a tall, wide throat opening to help move material smoothly without bridging. Closely set, heavy-duty rollers support the apron conveyor to extend belt life even under tough loading conditions.
