The plant’s innovative design and size are a claimed first of its kind for the industry, featuring an 8-foot-wide high-frequency screen.
Astec’s newest PTSC plant is equipped with an 8’ x 18’ (2.4 x 5.5m) top deck and an 8’ x 12’ (2.4 x 3.7m) bottom deck. The patent-pending screen design features externally-mounted vibrators at the ends of the tappets for a more aggressive screening action. This unique design creates a higher G-force and reduces heat load from material to motors as compared to single, centre-mounted vibrators. It also allows for easier maintenance and adjustments. The screen is equipped with hydraulic operating angle adjustment, a fines collection hopper, top- and bottom-deck discharge chutes and an aggregate spreader.
Similar to other PTSC plants, the 2818VM features a nominal 54'' x 38'’ (137.16 x 96.52cm) delivery conveyor with a hydraulic drive and full-length skirtboards. The chassis is fitted with manually-operating support legs, outriggers for additional support and folding walkways along the screen.
The new portable plant is available with a variety of options, including steel screen cloth, vinyl dust cover, hydraulic levelling jacks, immersion heaters for hydraulic reservoirs, starters for three off-plant conveyors and more.
