Astec Industries launches mobile high-frequency screen plant

Astec Industries’ Materials Solutions Group, an equipment manufacturer for asphalt road building, aggregate processing and more based in Chattanooga, Tennessee, recently launched a mobile high-frequency screening plant called the GT2612V.   

The plant features a 2612V Vari-Vibe high-frequency screen. The two-deck screen uses a rotary tensioning system that allows for quick screen media changes on the market, giving producers more uptime. The 2612V also has deck-mounted, variable speed hydraulic vibrators, a hydraulic mechanism for varying operating angles, a fines collecting hopper, top and bottom deck discharge chutes and an aggregate spreader. The screen can quickly and efficiently size crushed stone, recycled asphalt pavement, sand, gravel, coal and more.  

The mobile GT2612V is manufactured on a heavy-duty, welded steel main frame with a channel cross-section. The company says a walkway around the screen and remote grease lubrication for ground-level access make maintenance simple.   

The plant includes a large hopper with a capacity of eight cubic yards that is equipped with 6-inch sloped grizzly openings and a remote tipping grid. The hopper also includes foldable wings and hydraulic support legs. The variable-speed, 48-inch-wide belt feeder features a high-torque hydraulic drive, full-length impact bed, rubber lagged head pulley and self-cleaning wing tail pulley.   

The screen plant is equipped with four conveyors, including a delivery conveyor, two side conveyors and a fines conveyor. All conveyors feature a variable-speed hydraulic drive and easily fold for transport.   

The GT2612V is powered by a Caterpillar Tier 4 Final, 136 horsepower engine, while engine-mounted mounted hydraulic pumps operate all plant functions. The plant includes a PLC control system with pendant remote controls for the tracks.   

Additional options for the GT2612V mobile plant include engine alternatives like the Caterpillar Tier 3 and Stage V, 15-foot hopper/feeder in lieu of standard for additional capacity, heavier-duty grizzly section with replaceable grouser bar cartridge and more.
