Astec Industries’ Materials Solutions Group launched a portable high-frequency screen plant in the PTSC2818VM.

The plant is equipped with an 8-ft. x 18-ft. top deck and an 8-ft. x 12-ft. bottom deck. It also features externally-mounted vibrators at the ends of the tappets for more aggressive screening action.

Astec says the screen’s design creates higher g-force and reduces heat load from material to motors compared to single, center-mounted vibrators, allowing 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. 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, according to Astec.

The plant is available with a variety of options, including steel screen cloth, a vinyl dust cover, hydraulic leveling jacks, immersion heaters for hydraulic reservoirs, and starters for three off-plant conveyors.
