The Windshifter, also known as Pneumatic Concentrator, Waste Air Sorting Machine, garbage air sorting machine, wind screening equipment, airflow specific gravity sorting machine, air classifier and air drum separator, is a high-efficiency density sorting device core to municipal solid waste disposal (MSW) and waste treatment and recycling lines. It separates materials based on aerodynamic properties (density and particle size) using controllable positive and negative pressure airflow, seamlessly integrating with Conveyor Belt, Plate Feeder, Vibrating Feeder and other waste sorting equipment such as rotary trommel screen, Ballistic Separator, Magnetic Separator to improve sorting efficiency and purity, and perfectly matching waste shredder machine and Waste Baler in the whole waste processing line.
Composed of centrifugal fan, rotating separation drum, belt conveyor, light substance settling chamber, electrical cabinet and integrated dust filtration system, this equipment adopts industry-leading negative pressure technology and can be configured as semi-mobile or stationary, with a wear-resistant design for abrasive materials. It is easy to operate, with feeding conveyor adopting frequency conversion control, and can be connected with Waste Feeder, Apron Feeders and Municipal solid waste feeding system to adjust feeding speed according to air volume, wind speed and air pressure, adapting to mixed waste and stale garbage sorting needs.
Working Principle: Mixed materials, after preliminary processing by Double-Shaft Shredder or Plastic Shredder Machine, are fed into the separator (via Conveyor Belt or Waste plate feeder), and under the combined action of airflow and rotating drum, lighter materials (paper, plastic bags, films, cloth strips processed by textile shredder machine) are carried by the airflow to the settling chamber or distant discharge belt; heavier materials (metals separable by Eddy Current Separator, stones, glass, ceramics) fall naturally due to gravity or inertia to the heavy material discharge belt. The fan speed and dampers are adjustable to optimize sorting efficiency and purity, and the exhaust duct connects to a dust removal and deodorization system to meet emission standards, supporting the operation of waste sorting machine and garbage separation machine.
Key Parameters: Production Capacity: 20-75 tons/hour (or 30~260m³/h, adjustable by material type); Feed Particle Size: Suitable for mixed materials with large density differences (up to 200 mm); Power: 18.5-55kw (or 59kw for large models); Core Components: Centrifugal fan, separation drum, dust filtration system, electrical cabinet; Place of Origin: Henan, China.
Core Advantages: Efficiently separates light and heavy materials, especially bulky plastic film, and cooperates with Bag Opener to improve sorting effect; equipped with stone catcher to prevent duct blockage; low maintenance, few wearable parts, low energy consumption (with recirculation fan); wide applicability, stable operation and good sorting effect, suitable for matching with Vibrating Screen, Star Screen and Sorting Robot; cyclone system improves working environment and reduces air pollution; adjustable airflow to adapt to different materials such as construction waste, construction and decoration waste and landfill stale waste.
Applicable Scenarios: Widely used in municipal solid waste disposal (MSW), C&D waste, C&I waste, WEEE, MBT, RDF/SRF, ASR, landfill mining, recycling plants, waste management facilities, papermaking plants, wastewater treatment plants and agricultural waste processing. Suitable for sorting household waste, industrial solid waste, papermaking waste, textile waste processed by textile shredder machine, leather waste, construction waste, construction and decoration waste, landfill stale waste, mixed waste and construction mixed waste, facilitating subsequent recycling and utilization, and can be integrated with horizontal baler machine, Hydraulic Baling Press for post-processing.
