Astec launch new portable high-frequency screen
With its innovative design and size, the PTSC2818VM is said to be first of its kind in the industry
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 said to be the first of its kind in the industry, featuring an 8ft-wide high-frequency screen.
The new PTSC plant is equipped with an 8ft x 18ft (2.4m x 5.5m) top deck and an 8ft x 12ft (2.4m 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 is said to create a higher G-force and reduce heat load from material to motor, compared with single, centre-mounted vibrators. It also allows for easier maintenance and adjustments.
The screen is also equipped with hydraulic operating angle adjustment, a fines collection hopper, top- and bottom-deck discharge chutes, and an aggregate spreader.
Like other PTSC plants, the 2818VM features a nominal 54in x 38ft delivery conveyor with hydraulic drive and full-length skirtboards. The chassis is fitted with manually operated support legs, plus outriggers for additional support, and folding walkways along the screen.
The new portable plant is available with a variety of options, including, among others, steel screen cloth, a vinyl dust cover, hydraulic levelling jacks, immersion heaters for hydraulic reservoirs, and starters for three off-plant conveyors.
