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.

The Nihot Drum Separator is an effective separating solution using controlled air. It is utilized toseparate and/or upgrade various waste qualities, such as Municipal Solid Waste or Construction & Demolition Waste and other waste materials. It processes many different waste streams very efficiently, including:

  • larger fractions
  • bulky soft materials
  • 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

Features & Advantages

For over fifteen years, we’ve been recognized as innovators in the grinding equipment industry with several unique machines and patented features. These innovations form the “Perfect In One Pass” difference that defines our customers’ success stories.

Colorizer System

This patented system allows operators to grind and color virtually any clean wood fiber virtually any color. The power application system injects water and colorant directly into the grinding chamber to offer the most efficient means of producing colored landscape mulch. Utilizing the force of the grinding process to mix colorant into mulch ensures thorough color application without hassle and waste.

Bale Pre-Processing System

Our unique bale pre-processor separates round or square bales into an even flow of loose material to the grinding chamber, optimizing efficiency and throughput. Fully integrated into the grinder’s control system, the bale pre-processor automatically adjusts its operating parameters according to bale consistency and will actually unroll round bales rather than simply tearing them apart unevenly.

Slab Ramp

This Rotochopper exclusive allows our horizontal grinders to efficiently process pliable feedstocks that can plug other grinders, like green slab wood, palm fronds, tomato vines, and various forms of agricultural residue. Simple and reliable, with no moving parts to break down, this patented feature lets operators quickly adjust the angle and speed at which feedstock enters the grinding chamber, creating an aggressive feeding angle appropriate for solid materials, and a less aggressive angle for pliable feedstocks.

StopWatch Monitor and Control System

Designed to reduce downtime and damage from severe rotor impacts, our patented StopWatch system stops and reverses the infeed when it detects excessive vibration. Integrated into the electronic control system, the StopWatch system monitors vibration directly from a rotor bearing and records an operating log of vibration levels to help operators manage maintenance and operating practices.

Replaceable Mount Rotor

Simple yet solid, this rotor (patent pending) allows operators to quickly change rotor mounts using only two bolts—no bushings, lock collars, or pins. Its unique design minimizes impact stress experienced by the mounting bolts. If one mount becomes damaged, only one needs to be replaced.

Unequal-length Powerfeed Linkage Arms

This innovative powerfeed lift system (patent pending) keeps the powerfeed close to the rotor throughout its lift path, in contrast to traditional powerfeed arms that widen the distance as the powerfeed rises. This lift assembly can generate remarkable downward pressure with little effort and applies this force close to the rotor, where it is most effective at controlling the feed rate.

90-degree Side Loading Conveyor

When equipped with this option, our horizontal grinders can fill parallel open top semi trailers. The 90-degree side loading conveyor reduces downtime required to position the grinder and trailer in cramped operating environments like forestry landings.

Rotating Anvil

A key advantage of our asphalt shingle grinders, the rotating anvil (patent pending) force feeds a steady flow of raw material to the rotor to allow rapid, yet smooth, grinding. Designed for the abrasiveness and pliability of asphalt shingles, the rotating anvil experiences significantly less wear than typical anvils and enhance grinding efficiency.

Screen Installation System

All of our grinders and chip processors allow fast, convenient rotor access and screen changes with our unique screen installation system. Screens can be changed in as little as fifteen minutes without additional tools.

Aggressive Powerfeed

Each of our horizontal grinders features an aggressive powerfeed drum with deep serrated teeth. Combined with a steel slat infeed conveyor, the powerfeed drum provides controlled feed rates for vastly different feedstocks: whole trees, pallets, wood chips, tomato vines, green slab wood, corn stover, yard waste, and much more.

Steel Slat Infeed Conveyor

Smooth steel slat infeed conveyors give our grinders the capacity to efficiently feed diverse feedstocks with less spillage and wear than drag chain conveyors. Our unique infeed transition system allows raw materials to flow smoothly from the infeed conveyor to the grinding chamber, preventing loose particles from falling directly onto the collection conveyor and decreasing finished product value.

Rotor, Tooth, & Screen Designs

A key to our “Perfect In One Pass” advantage is our focus on screen and tooth design. The right screens and teeth are essential to finished product control, and we offer a wide selection to maximize the versatility of our grinding equipment.

Advanced Electronic Control Systems

We use state of the art control systems to provide superior equipment control, monitoring, and diagnostic capabilities. User-friendly and reliable, our controllers take the guess work out of equipment settings, allowing operators to quickly make accurate adjustments to infeed speed and other settings.

Dust Control

Each of our grinders comes standard with a grinding chamber water injection manifold for suppressing dust. Injecting a small amount of water directly into the grinding chamber provides effective dust control. Our colorizer system provides the same dust control benefits. We offer several additional dust control options for sensitive environments; please call for details.

OEM Components

We use OEM components from industry leaders like CAT, PT Tech, and Flexxaire to guarantee the best combination of performance, reliability, and customer support. These OEM solutions allow us to suit the unique challenges of each customer with practical technology that is backed by world-wide service.

flip-flop screens

The perfect solution

Application range 
TRISOMAT-screens are ideally suited for the screening of:

  • Coal and coke
  • C&D waste
  • Sand and gravel
  • Municipal waste
  • Compost
  • Slag
  • Shredded materials


  • High feed rates

The perfect solution

Screens in this series are the optimal solution for extremely difficult materials. Where conventional screening machines become blocked or stuck, these screens provide excellent results at high feed rates, even with small mesh sizes. The unique ”3-phase-oscillation“ of the TRISOMAT screen ensures

  • rapid break-up of the material in the feed area itself
  • efficient screening in the central area
  • intensive ”near-size“ screening in the discharge area

The screen for difficult to handle materials

 The perfect solution

Operating principle

Circular movement in the feed area – rapid material break-up, high feed rates,even with challenging materials.

The linear movement in the central area ensures optimal contact between the material and screen mesh – efficient screening!

Elliptical movement against the direction of conveyance – improved material destratification and ”near-size“ screening.

Screen crossbeams are fitted on two frames (the external and internal frames respectively) that can be moved together. Flexible screen panels fitted onto these crossbeams are tightened and loosened alternately via the frame movements. High acceleration forces prevent the screen deck becoming blocked up or sticking.

The frame movements are generated by an eccentric drive. The special motion of both frame systems means that three different oscillatory movements are produced on the external frame.

 Optional features

  • Triple deck design
  • Other dimensions
  • Dust sealing-system Trellex
  • Chutes
  • Screen mats in various qualities/thicknesses
  • Bolted top cover
  • ATEX-design
  • Side sealing (if required)

Scalping – For scalping usually Grizzly feeders in heavy duty design are in operation.

They are used to feed crushers and mills, or as separating grates in the foundry industry.

Sizing – One of the main mechanical handling methods used for granular bulk material is screening. The type of material, the grain shape and grain size, humidity, output and screen cut size as well as a many other parameters necessitate a broad spectrum of different solutions.

Desliming-Deslurring-Dewatering – For this purpose more or less only linear vibratory screens are used today. They are in operation for recovering dense media in heavy media plants, for removing from very fine materials respectively dewatering of materials won or processed in a wet state to enable onward feeding on conveyor belts.

Individual solutions – In addition to conventional linear motion and circular motion vibrating screens, IFE offers special screening machines for very demanding duties. The optimal solution  for screening without clogging of material difficult to screen.
