The Windshifter, also known as Pneumatic Concentrator, Air Sorting Machine, garbage air sorting machine, wind screening equipment, airflow specific gravity sorting machine, air classifier and air drum separator, is a core high-efficiency density sorting equipment for municipal solid waste sorting line, construction and demolition waste recycling plant, landfill mining processing and solid waste resource recovery project. This professional waste air separation equipment sorts materials relying on aerodynamic density and particle size difference via adjustable positive and negative pressure airflow. It perfectly matches the full set of waste sorting equipment including Conveyor Belt, Plate Feeder, Vibrating Feeder, rotary trommel screen, Ballistic Separator and Magnetic Separator, greatly improving sorting purity and recycling rate, and forms a complete closed-loop processing flow together with waste shredder machine and Waste Baler in the full automatic garbage disposal production line.

Manufactured and optimized by Henan Ruichi Machinery, this air gravity separator consists of centrifugal fan, rotating separation drum, belt conveyor, light substance settling chamber, independent electrical cabinet and integrated dust filtration and deodorization system. Adopting mature negative pressure wind sorting technology in the solid waste recycling industry, it supports semi-mobile skid-mounted type and stationary fixed type installation, with overall wear-resistant structural design for long-term handling of abrasive mixed garbage materials. The feeding conveyor adopts frequency conversion speed regulation, which can be docked with Waste Feeder, Apron Feeders and complete municipal solid waste feeding system. Users can freely adjust feeding speed matching air volume, wind speed and air pressure, fully adapting to mixed domestic waste, construction decoration waste and landfill stale garbage light-heavy separation demands.

Working Principle:

After pre-crushing treatment by Double-Shaft Shredder or Plastic Shredder Machine, mixed waste materials are evenly sent into the windshifter through Conveyor Belt or Waste plate feeder. Under the combined action of stable circulating airflow and rotating separation drum, light impurities including waste paper, plastic bags, plastic films, cloth strips and textile leftovers processed by textile shredder machine are carried by airflow into the light material settling chamber and discharged separately; high-density heavy materials such as metal scrap (subsequent sorting by Eddy Current Separator), stones, glass and ceramics fall to the heavy material discharge belt by gravity and inertia. Fan rotating speed and air damper can be precisely adjusted to upgrade overall sorting efficiency and separation purity. The rear exhaust duct is connected with professional dust removal and deodorization equipment to meet environmental emission standards, which is an essential supporting machine for automatic waste sorting machine and garbage separation production line.

Key Parameters:

Production Capacity: 20-75 tons/hour (or 30~260m³/h, adjustable according to waste composition); Feed Particle Size: Suitable for mixed materials with large density difference, maximum feeding size up to 200 mm; Matching Power: 18.5-55kw (59kw optional for large industrial models); Core Configuration: Centrifugal circulating fan, anti-wear separation drum, integrated dust filtration system, intelligent electrical control cabinet; Manufacturer & Origin: Henan Ruichi Machinery, Henan China — professional supplier of full-set waste sorting and recycling production line solutions.

Core Advantages of Henan Ruichi Windshifter:

Our pneumatic air sorting machine realizes precise light and heavy material separation, especially ideal for bulky plastic film and lightweight combustible waste separation. Matched with Bag Opener, it further improves the overall garbage sorting effect. Equipped with built-in stone catcher device to effectively avoid pipeline blockage caused by hard sundries; it features simple structural layout, few vulnerable parts, low daily maintenance cost and low energy consumption with circulating air duct design. With stable continuous operation and high sorting accuracy, it can be perfectly combined with Vibrating Screen, Star Screen and intelligent Sorting Robot to form an integrated sorting system. The independent cyclone dust removal system optimizes on-site working environment and reduces secondary air pollution. Adjustable airflow and wind pressure adapt to multiple material types, including construction waste, construction & decoration waste, industrial solid waste and landfill mining stale waste. Henan Ruichi provides one-stop customized layout design, equipment matching, installation guidance and lifelong after-sales service for global waste recycling project investors.
