Glass Sorter for CSP separation

The REDWAVE IR is an optical sorting machine for glass recycling. In the first step, the machine seperates CSP (ceramics, stones, porcelain), ferrous and non-ferrous metals from the recyclable material stream. A vibration feeder provides a constant flow of infeed material evenly spread over the entire sorting width of the REDWAVE machine.

Sensor system:


Machine data:

  • Sorting width: 900mm
  • Cullet size: from 8 – 50mm
  • 36 Valves with 144 Air Jets
  • Capacity: 6 – 8 t/hr (depending on cullet size)


Glass C for colour recognition

The REDWAVE C is an optical sorting machine used either for colour improvement of pre-sorted flint, green or amber glass or for full colour sorting of mixed cullet. A vibration feeder provides a constant flow of infeed material evenly spread over the entire sorting width of the REDWAVE machine.

Sensor system:

High-resolution RGB camera

Machine data:

  • Sorting width: 1000 – 1300mm
  • Cullet size: 3 – 60mm
  • Design: 2-way or 3-way machine
  • Capacity: up to 12 t/hr (depending on cullet size)


Glass Sorter for material and element separation

The REDWAVE XRF-G sorting machine is mainly used for the separation of leaded and ceramic (heat resistant) glass. The glass is analysed and valued on the basis of its chemical compounds by X-Ray Fluorescence Spectroscopy. During the process, the system searches for certain elements like Titanium, Zinc, Zirconium or Lead. Identifying these elements enables a precise categorization of the infeed material. Undesired parts can be reliably detected and separated from the main stream. This sorting machine was developed in collaboration with the American company Olympus ANI-Systems, who specialize in X-Ray Fluorecence Technology.

Sensor system:

EDXRF Spectrometers

Machine data:

  • Sorting width: 760 – 1370mm
  • Capacity: up to 28 t/hr (depending on the tasks and cullet size)


  • Separation of ceramic glass and leaded glass in a single machine in a single sorting process
  • Even if the glass is heavily contaminated, reliable separation is guaranteed

Eddy Current

At JDM Aust we only offer what we believe is the best possible technology available, IFE Eddy Current Separators are used worldwide and are considered one of the best in the world today. Please contact us for further information.

IFE Eddy Current Separator

 As the need to continually stream line and effectively separate the recyclable materials from our ever growing waste streams Eddy Current Separators have played an integral role in the separation of Non-Ferrous metals from our waste streams such as MSW, C&D, C&I, Green Waste, RDF’ s, Electronic Scrap and Metal recycling just to name a few. IFE Eddy Current Separators are used worldwide for this application and are considered one of the best in the world today as we use only the best magnetic material available. IFE supply a wide range of Eddy Current Separators ranging from production widths of 500mm, 1000mm, 1500mm, 2000mm and the world’s first 2500mm wide production unit.

Benefits of the IFE-eddy current separator

  • High separation capacity
  • High purity of separated fractions
  • Special arrangement of magnetic system
  • Use of the best magnetic material
  • Compact solution for ferrous and non-ferrous separation


The eddy current effect appears if nonferrous conductors of electricity are exposed to a magnetic alternating field.The eddy currents in turn generate magnetic fields whose flux are opposed to the fields generating them, thus causing repulsive forces which discharge nonferrous metals out of the material flow.


The IFE eddy current metal separator consists of a belt conveyor with two tail pulleys.The driving drum on the feeding side is driven by a geared motor, the belt speed can be electronically adjusted by continuous control. An extremely strong, fast rotating permanent magnetic system is located in the head pulley. The specific geometry of the magnetic system generates a pulse like magnetic field. The number of revolutions of the magnetic field is also continuously adjustable and can thus be adapted to the individual cases. The whole machine is a modular construction on a base frame (feeder, Eddy Current Separator, splitter unit) which can be easily transported and installed. An extensively equipped control makes possible an optimum adaptation to the respective charging material, thus ensuring best separation results.

Details and principles windshifter

The Nihot Windshifter is a combination of a recirculation fan, a separation unit and a combi separator.

Process description

It separates the input into two fractions, light and heavy. In the separation unit (the sifter unit) the heavy materials are separated from the light materials. The lighter materials are transported (by controlled air flows) to the combi separator, where the materials will be separated from the air stream. In stead of a combi separator, a rotary air separator can be used in a windshifting system.

  • products with relative higher moisture content

The Nihot Drum Separator is one of our air-controlled separation solutions, which is an ideal medium to separate waste based on density of the material. It has a highseparation efficiency of up to 99 %.

The Nihot Drum Separator has a capacity of up to 100 tonnes/hr of input and up to 25 tonnes/hr of separated light fraction. It can handle large fraction sizes (e.g. film and plastic bags) easily.

A dust suppression system is essential to meet local and international Health & Safety regulations and to comply with environmental directives and regulations with regard to dust emission.

Nihot offers turn-key dust suppression systems for the Environmental and Recycling Industry, more specifically for waste sorting and recycling facilities.

In general, our dust control solutions give the tools to minimize, control and monitor dust emission, and to improve the air quality considerably.

We realize dust suppression systems on a turnkey basis,including:

  • The design, engineering and manufacturing of all the necessary dust hoods, air ducting, ventilators, filter units, etc.
  • Supervision during assembly on site, testing, commissioning and training.

Types of dust suppression systems

  • A primary dust suppression system
  • A secondary dust suppression system
  • Dust suppression / air treatment in e.g. hand picking stations

Primary Dust Suppression

 Specific units in a waste sorting or recycling facility (such as shredders, screens, shifters, transfer chutes on conveyors, separators) are connected to a dust suppression system, building up a fully closed system.


Secondary Dust Suppression

Secondary dust suppression is an extraction of the whole volume of a building, followed by a cleaning process. After that the air will be returned (partly) to the building and/or emitted into the open air.

Dust Suppression / Air Treatment in Enclosed Spaces

An air treatment system that guarantees a pleasant work environment, creating excellent interior air quality and conditions in e.g. hand picking stations (sorting cabins). The system preconditions air prior to feeding it to the enclosed space, while changing the volume up to 6 or 10 times per hour.

The Nihot Rotary Air Separator (RAS) separates waste materials (fractions) from the conveying airflow by passing it over a perforated screen.

A few advantages of the Nihot Rotary Air Separator:

  • It has a stainless steel separator screen to prevent dust to become electro static, i.e. self cleaning.
  • Fully sealed, dust free operation.
  • 3 large hatches for easy access for inspection/maintenance purposes.



The Rotary Air Separator is applied:

  • As a stand alone system in specific airflows like paper or cardboard. Possible to place it directly above a baler.
  • In combination with a Nihot Windshifter to separate the light fraction from the airflow.
  • To separate any light fraction from the exhaust airflow from a Windshifter and/or Drum Separatorto prevent particles to enter the filter unit.

For smaller volumes, a Rotary Air Separator can be used in combination with a Nihot Windshifter.


Typical applications Rotary Air Separator

in main airflows: in secondary airflows:
  • Paper
  • Cardboard
  • Plastic film
  • Wood chips
  • RDF / SRF
  • Film vacuum systems
  • Light fractions from windshifters
  • Light fractions from Drum Separators
  • Light fractions from WEEE separation
  • Light fractions from glass clean up







How does the RAS function?

 The waste materials are separated from the conveying airflow by passing it over a perforated screen.
1. The clean airflow is discharged horizontally into a filter unit or returned to the main air system in close loop.
2. The separated materials are vertically discharged via a rotary valve for further processing.
The Nihot Rotary Air Separators are supplied in various sizes ranging from 22.000 m3/h up to 55.000 m3/h airflow. Those type of separators process fractions from 5 up to 200 mm.

Nihot has developed a unique method of taking out film, plastics and foils from waste streams in sorting cabins. We call this our Film Vacuum System.
The Film Vacuum System consists of one or more suction points, a re-circulation fan, and a material/air separator. The complete systems works in a closed loop. This means that the air which is used to suck the material is 100% brought back into the system.
The material which is (manually) brought to the suction point, is sucked into suction hood and pneumatically conveyed to a Rotary Air Separator or Combi Separator where the material is dropped pressure less onto a conveyor belt or storage bay.
The main advantages are:

  • Closed loop system
  • No surrounding air is extracted
  • No (air) conditioning of sorting cabin needed
  • Can be easily retro fitted
