Size / Volume Reduction

Shredding of metals for volume reduction can simplify material handling, minimize storage space and reduce transportation and disposal costs. SSI has built shredders to process light scrap in a metal recycling yard, or materials generated by a manufacturer, such as aluminum extrusion from a door or window manufacturer. SSI shredders have also been used to prepare metals to feed into high-speed hammermills.

Recycling / Remelting

Metals destined for recycling are often baled or briquetted to facilitate handling and reduce transportation costs. However, once material arrives at the processing facility, processors often wish to shred bales or briquettes to improve furnace feeding and the efficiency of the remelting or delacquering process. Shredding also helps to liberate trapped contamination, upgrading the quality of the metal and its value.

Precious Metal Recovery

Electronic scrap including computer drives, monitors, telephone-switching gear, and circuit boards contain precious metals such as gold, silver and platinum. Recovery facilities have used SSI low-speed shredders to preprocess bulky components to make it easier to liberate metals.

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.

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
