en.Wedoany.com Reported - Large quantities of waste asphalt millings (RAP) generated during road maintenance and pavement rehabilitation often face problems such as occupying land for stockpiling, non-environmentally friendly landfill disposal, destruction of gradation by traditional crushing methods, equipment blockages, and high maintenance costs. Recently, Liaoyuan Road Machinery launched the 3PS80 asphalt recycled material crushing and screening plant, specifically designed for efficient RAP processing, providing a one-stop solution.
This asphalt recycling equipment adopts dual-roller flexible fine crushing technology, processing recycled material through interlocking and kneading action without destroying the original gradation and protecting the asphalt coating layer. The roller gap is adjustable, with a discharge range of 0–30 mm, and it features a self-cleaning function to prevent material sticking and blockages. The three-stage precise screening system uses a triple-deck linear screen to separate materials into three finished product grades: 0–8 mm, 8–14 mm, and 14–25 mm. The mesh sizes can be customized as needed, and combined with anti-clogging screens and flexible knocking, it ensures smooth screening of sticky, wet asphalt materials.
The asphalt recycling equipment adopts a closed-circuit circulation design, where oversized materials are automatically returned for re-crushing, achieving a full-process closed loop with a 100% qualified discharge rate and high resource utilization. It has a production capacity of 60–80 tons per hour, a total power of approximately 58 kW, low energy consumption, and stable operation. The entire process includes uniform feeding, iron removal protection, precise screening, and circulating crushing, requiring no complex operations or large amounts of labor, and can transform waste millings into high-value recycled aggregates.
The Liaoyuan 3PS80 equipment is suitable for mixing plants and road maintenance projects, helping to reduce the procurement of new materials and lower production costs, while meeting environmental protection and green construction requirements, achieving a win-win situation for both economic and environmental benefits.
