Asphalt Recycling Aggregate Crushing and Screening System

Asphalt Recycling Material Crushing and Screening System

The asphalt recycling aggregate crushing and screening system is a core piece of equipment in the field of asphalt pavement recycling, integrating intelligent crushing, efficient screening, and environmental friendliness in one. Designed based on Industry 4.0 principles, this equipment features a modular architecture and is specifically tailored for the recycling of reclaimed asphalt pavement (RAP) materials. It can transform old materials into high-quality recycled aggregates, significantly enhancing resource utilization and making it a key technological tool for achieving the "zero waste" goal in road construction projects.

Core Highlights and Advantages

1. Innovative modular design, flexible and efficient

The equipment features a standardized, modular system architecture. Its core components include an intelligent feeding system, a RAP-C80 dual-tooth roller crusher main unit, a three-stage probabilistic screening system, and a closed-loop conveying system. This design not only allows for flexible production line layouts and easy installation and maintenance but also enables rapid adaptation to different processing capacities and site requirements. Moreover, it holds great potential for expansion into areas such as construction and demolition waste treatment.

II. Breakthrough in Core Technologies: Achieving Both Quality and Performance

1. High-efficiency and energy-saving crushing: Utilizing specialized double-tooth roller crushing technology, the specific energy consumption is as low as 0.8 kWh/t, representing a 42% reduction compared to conventional equipment and significantly lowering operational costs.

2. Excellent Aggregate Retention Rate: By optimizing the crushing principle, we significantly reduce over-crushing and the formation of needle- and flake-shaped particles, ensuring the integrity and high value of recycled aggregates.

3. Active and Highly Efficient Retention: An innovative process ensures that the coating rate of asphalt after crushing remains stable at over 92%, and it boosts the activation efficiency of aged asphalt by 35%, thereby guaranteeing the activity of recycled materials and the performance of the resulting mixtures.

III. Significant Green Benefits, Quantified Emission Reductions

The equipment boasts outstanding environmental benefits; processing 100,000 tons of RAP material per year per unit can directly be equivalent to:

*Reduced natural sand and gravel mining by approximately 160,000 cubic meters

*Reduced carbon dioxide emissions by 12,000 tons

Strongly supports green construction and the achievement of the “dual carbon” goals.

4. Intelligent operations and maintenance to ensure continuous production

The integrated IoT monitoring and remote diagnostics system enables real-time monitoring of equipment operating status, facilitating predictive maintenance and rapid fault response. It reduces the mean time to repair (MTTR) to under 2 hours, significantly enhancing production continuity and management efficiency.
