Wind shifter
Double Drum Windshifter

The DDW2000 Double Drum Windshifter is a high-performance air separation system developed by Harden for solid waste recycling and RDF/SRF production. With its dual-drum structure and closed-loop airflow design, the system accurately separates mixed waste into three fractions (light, medium, and heavy).


Its double-drum configuration supports continuous, high-volume processing and maintains stable performance when handling flexible, elongated, or bulky materials. It is an essential piece of equipment for large-scale solid waste pre-treatment and resource recovery operations.

High-Precision Sorting
High-Precision Sorting
The dual-drum structure enables accurate separation into light, medium, and heavy fractions, delivering high sorting precision and significantly increased throughput.
Energy-Efficient Airflow Design
A closed-loop airflow system recirculates internal air to minimize fresh-air demand and effectively reduce fan energy consumption.
Low Dust Emissions
A micro-negative-pressure system combined with an efficient dust collector reduces dust release and minimizes environmental impact.
Multi-Dimensional Sorting Control
Adjustable valves allow flexible tuning to accommodate materials of different densities and particle sizes, achieving more precise sorting control.
Flexible Layout Adaptation
The tail settling chamber and discharge conveyor support both horizontal and inclined configurations to suit various site layouts and operating conditions.
Clean Operating Environment
Multi-stage cleaning and sealing at the feed and discharge sections minimize material leakage, ensuring a clean and safe working area.
Easy-Maintenance Structure
External drive and inspection access, combined with an automatic lubrication system, reduce maintenance frequency and labor costs.
Air Duct Filtration Protection
Built-in air-duct filters reduce equipment wear, lower maintenance frequency, and enhance overall system reliability.
