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.
