Air Knives & Waste Separation Systems

Problems & Considerations

With the global commitment to improving the environment, the type and amount of waste being sent to landfill is becoming ever more closely controlled.

Recycling of waste materials, either commercial or domestic, is at the forefront of reducing the load on landfill sites using automated or manual recycling facilities.

An important aspect of these recycling facilities is finding an effective and cost efficient solution to the separation of ‘lights’ materials (i.e. paper, plastics etc.) from the heavier materials at the conveyor transfer points .

The Answer?

  • KEE Air Knife systems form and integral part of many new waste recycling facilities.
  • Our systems provide quality separation/ segregation of individual waste types using air movement and conveying systems.
  • Typical applications allow for the removal of ‘lights’ materials and separation of 2 and 3 dimensional waste types.

Components

KEE air knife systems are available in three designs:

  • Standard Air Knife
  • Conveying Air Knife (static screen)
  • Conveying Air Knife (rotary screen)

The standard air knife system consists of low pressure or high pressure blower fans connected to adjustable, nozzle type, air knife head assemblies.

The systems separate the ‘lights’ materials from the conveyor transfer points and direct them to either collection bins or skips.

In the case of the static screen or rotary screen conveying air knives, an additional materials handling fan is installed on the collection side of the transfer point to allow the material to be conveyed over long distances using a centralised ductwork main. This allows the ‘lights’ waste collection to be located wherever required.

The waste can also be directly discharged onto conveyors in any location throughout the recycling facility.  A further advantage is that the motive dust laden air is contained within a ductwork line, enabling a dust control plant to be easily installed if required.
