What is an High Density Windshifter ?
FXG Series High Density Windshifter, also known as a density air separator or high-density air classifier, separates materials based on density differences through adjustable airflow. Compared with standard wind sifters, it is designed for more accurate separation of heavy and light fractions in C&D waste, MSW, industrial waste, and RDF production lines. It is commonly installed after shredders and screening equipment for further material classification.
The High Density Air Separator is available in four models to meet different processing requirements. Depending on the model, it operates with an air volume of 20,000–40,000 m³/h, air pressure of 2,000–3,500 Pa, a maximum feed size of up to 300–400 mm, and power ratings from 22–45 kW.
Xinzhongyi ECO manufactures customized FXG Series High Density Windshifters according to material composition, capacity, and plant requirements. We have 16+ years of recycling equipment experience, we provide equipment manufacturing, process design, installation guidance, and commissioning support. The system can be integrated with magnetic separators, eddy current separators, and optical sorting equipment for complete recycling lines.
Working Principle
A High Density Air Separator separates mixed materials by combining controlled airflow with differences in material density. Mixed waste is fed into the machine, evenly dispersed, and passes through an adjustable airflow zone. Light and heavy materials follow different paths according to their density, enabling continuous air separation without water or manual sorting.
Heavy materials such as stones, glass, and metals are discharged from the heavy fraction outlet, while paper, plastic film, wood, and textiles are carried into the settling chamber for collection. Xinzhongyi ECO designs High Density Air Separators to match different material characteristics, processing capacities, and plant layouts. The equipment can be integrated into complete recycling lines with engineering support, installation, and commissioning services.
Parts
The High-Density Air Separator consists of a feed conveyor, air distribution unit, separation chamber, dual centrifugal blowers, cyclone collectors, and air return ductwork. The modular bolted structure provides reliable sealing, convenient assembly, and stable system operation.
Feed Conveyor
Delivers material at a uniform feed rate to maintain stable separation conditions.
Air Distribution Unit
Adjusts airflow volume and direction to suit different material properties and separation requirements.
Dual Centrifugal Blowers
Two independent blower units perform primary and secondary air separation, improving the removal of light fractions and overall separation efficiency.
Cyclone Collectors
Separate and collect lightweight materials from the air stream while reducing dust carryover.
Air Return Ductwork
Returns process air to the system, maintaining stable airflow and reducing operating energy consumption.
