Astec Industries’ Materials Solutions Group launched the GT2612V as a mobile high-frequency screening plant. 

The plant features a 2612V Vari-Vibe high-frequency screen. According to Astec, the two-deck, 6-ft. x 12-ft. screen uses a rotary tensioning system that allows for quick screen media changes. 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, Astec says.

The GT2612V is manufactured on a 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 company adds.

The plant’s hopper has a capacity of 8 cu. yd., and it is equipped with 6-in.-sloped grizzly openings and a remote tipping grid. The hopper includes foldable wings and hydraulic support legs. The variable-speed, 48-in.-wide belt feeder features a high-torque hydraulic drive, a full-length impact bed, a rubber-lagged head pulley and a self-cleaning wing tail pulley. 

The 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, Astec says.

A 136-hp Tier 4 Final engine from Caterpillar powers the GT2612V, and engine-mounted hydraulic pumps operate all plant functions. The plant includes a PLC control system with pendant remote controls for the tracks.
