Astec Industries’ Materials Solutions Group has designed and launched its newest portable high-frequency screen plant, the PTSC2818VM. The plant’s innovative design and size is the first of its kind for the industry, featuring an 8-ft.-wide high-frequency screen.
Astec’s newest PTSC plant is equipped with an 8- x 18-ft. (2.4 x 5.5 m) top deck and an 8- x 12-ft. (2.4 x 3.7 m) 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, center-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-in. x 38-ft. (137.16 x 1,158.2 cm) delivery conveyor with 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 leveling jacks, immersion heaters for hydraulic reservoirs, starters for three off-plant conveyors and more.
