Equipment and technology updates for aggregate producers

Astec Industries’ Materials Solutions Group launched a high-frequency portable 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 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.

Heavy-duty breakers built to last

Mazio Attachments says the XL Series of hydraulic rock breakers provides reliable performance in demanding environments such as quarries. Designed for carriers ranging from 1 ton to 140 tons of operating weight, the company says Mazio hammers feature a closed case built from 100 percent Hardox steel to protect the body from wear and impact. This, Mazio says, sets the breakers apart. Standard features include anti-blank-fire technology that minimizes wear, an energy-recovery system that reduces the required oil flow and a double-damping system that results in less vibration. Variable-impact speed and power can be manually tuned using an Allen tool, allowing the operator to adjust the breaker for correct productivity.
