“This new trommel screen can fit into a smaller space than our other models, which is a requirement for customers who have a limited amount of space on their site,” said Jeff Bradley, product manager for recycling and forestry at Vermeer. “We listened to contractors who told us they wanted a trommel that could produce three separate products without running the material through the machine twice. That is why we developed the optional third conveyor.”


The standard TR620 is equipped to separate material into two sizes based on screens selected. The optional front fines conveyor permits the creation of three unique products from incoming material without the need for another processing step or additional machine. The front fines conveyor can be mounted on either side of the trommel screen for additional jobsite flexibility.


As with the other Vermeer trommel screens, the TR620 features the intuitive Vermeer ACS control system. The TR620 can be controlled through either the Vermeer DP10 display, which is mounted on the machine’s control panel, or with a handheld transceiver remote. This allows the operator to have complete control of the trommel whether standing nearby or operating from a loader. Four user-defined program buttons enable operators to easily return to previously used settings when screening multiple material types. The remote also gives the flexibility to make immediate adjustments when incoming material type or volume changes. Operators can also adjust the conveyor height from the remote if necessary to help reduce blowing material.


Quick-change tensioned screens help reduce the time required to change screens, which is especially important when processing a wide range of materials that require different end products. A large door allows for drum access and removal in addition to providing ease of serviceability. Square lift bars inside the drum enable more material to be processed at a slower speed, helping to reduce fuel consumption and prolong drum life.


The TR620 features a 120-horsepower (89.5 kW) Cummins Tier 4 Interim (Stage IIIB) engine that meets all U.S., Canada and European emissions standards.
