Air Drum Separator (ADS)

The ADS is used to separate a mixed stream of material into heavy and light components for further processing.

Solution Overview

The ADS is a specially adapted air knife separator unit working in conjunction with a rotating drum and is designed to separate a wide variety of materials based on density, shape and aerodynamic properties. Used for separating a mixed stream of material into heavy and light components.

This is done using a forward upward facing air knife nozzle mounted at the end of a material in-feed conveyor. Mixed material falling from the in-feed conveyor then passes through the high velocity air stream and is either carried over the drum or is unaffected and falls in front of the drum.

The use of the drum is the latest development in material separation technology and utilises fluid dynamics principles to greatly improve the efficiency of the air stream once it has left the confines of the air nozzle, resulting in greatly improved separation.

Advanced Separation Technology

  • Separation of material based on density and shape
  • Very high hourly throughput levels achievable
  • Fully adjustable airflow controls via electronic fan speed controls
  • Outstanding results to significantly improve the separation of the material stream
  • Best suited for: C&D, C&I, WEEE, MBT, RDF/SRF, MSW, ASR and many more
  • Few wear items, low maintenance and highly reliable
  • Available in three standard widths, 1000mm, 1500mm and 2000mm (other configurations available on request)

Case Study

Construction & Demolition (C&D) - PVT Landfill, Hawaii

Impact Air Systems were contracted to install an Air Drum Separator (ADS) at the PVT landfill site, Hawaii.

The ADS’ purpose is to separate light and heavy material from a stream of construction and demolition waste. The throughput of material is around 30 tonnes per hour and the material size varies from around 2.5cm-25cm. The material is composed of fuel feedstock (wood, paper, plastic, carpet etc), rock, ferrous metal, non-ferrous metal and 0-25mm fines.
