Astec GT612V

High Frequency Screen

Astec Industries’ Materials Solutions Group has launched its newest mobile high frequency screening plant, the GT2612V.

The plant features a 2612V Vari-Vibe™ high frequency screen. The two-deck, 6’x 12’ (1.8 x 3.7 m) screen uses a unique rotary tensioning system that allows for some of the quickest 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 high frequency screen can quickly and efficiently size crushed stone, recycled asphalt pavement, sand, gravel, coal and a variety of other materials.

The mobile GT2612V is manufactured on a heavy-duty, welded steel main frame with a channel cross-section. 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 (15.2 cm) sloped grizzly openings and a remote tipping grid. The hopper also includes foldable wings and hydraulic support legs. The variable-speed, 48-inch (122 cm) 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: 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 hp (101.4 kW) engine, while engine-mounted hydraulic pumps operate all plant functions. The plant includes a PLC control system with pendant remote controls for the tracks.
