Harden Double Drum Windshifter DDW2000: Advanced Air Separation for RDF and Resource Recycling
Harden Machinery Ltd. presents the Double Drum Windshifter DDW2000, a high-performance air separation system designed for RDF/SRF production and solid waste resource recovery.
Compared with conventional single-drum windshifters, the dual-drum configuration provides higher throughput, enhanced separation performance, and increased operational efficiency for mixed solid waste processing.
Dual-Drum Technology for Precise Three-Way Separation
Powered by advanced negative-pressure aerodynamics, the DDW2000 processes input materials in a single pass. Its innovative dual-drum configuration cleanly splits the waste stream into three distinct output fractions based on density and size:
1. Light Fraction: High-calorific materials such as plastics, paper, films, and textiles.
2. Mid-Heavy Fraction: Recyclable materials like wood, rigid cardboard, and similar items.
3. Heavy Fraction: Inert materials, including stones, glass, metals, and aggregates.
This three-way separation provides a stable and efficient foundation for downstream recycling or fuel preparation processes.
Versatile Applications: From Waste to Value
The DDW2000 is designed to optimize the recycling value chain across diverse sectors:
· RDF & SRF Fuel Production: In MSW and landfill mining projects, the system effectively extracts high-calorific light materials for RDF and SRF preparation, while removing heavy non-combustible components to reduce wear and potential damage to downstream shredders.
· Construction & Demolition (C&D) Waste Recycling: The system effectively isolates heavy inert materials (concrete, stones) from mid-heavy fractions (wood). This produces clean, high-quality aggregates ready for reuse while recovering wood for biomass energy.
· Complex Material Recovery: Processing Commercial and Industrial (C&I) waste often involves entangled fibers and films. The DDW2000’s robust design adapts to these complex compositions, ensuring continuous, high-volume operation.
Operational Excellence & Efficiency
Designed for long-term reliability and sustainability, the DDW2000 offers:
· Adjustable Precision: Operators can fine-tune the separation drums, feed conveyor positioning, and internal valves to adapt to varying material densities, maximizing output purity.
· Energy Efficiency: The system utilizes closed-loop air recirculation technology, significantly reducing fresh air demand and lowering energy consumption.
· Clean & Safe: A fully sealed negative-pressure design effectively prevents dust leakage, ensuring a compliant and safe workspace.
· Smart Maintenance: Features such as modular detachable feed conveyors and an intelligent fan monitoring system simplify maintenance tasks and extend equipment lifespan.
With its proven reliability and adaptability, the Harden Double Drum Windshifter DDW2000 is the ideal choice for operators seeking to maximize resource recovery rates and ROI.
