Eddy Current Separator ECS / Non-ferrous metals separators
The Eddy Current Separator (ECS) is used to separate metallic (ferromagnetic and non-ferromagnetic) materials from non-metallic ones. This magnetic separator of non-magnetic metals works on the principle of so-called eddy currents induced by a magnetic cylinder. A magnetic cylinder (separator rotor) with very strong neodymium magnets is embedded in the conveyor. At high revolutions (when the magnetic poles alternate rapidly) it creates a magnetic field that magnetizes even non-ferromagnetic metallic materials for a short term. The magnetic polarity of the particles magnetized in this way is the same as the polarity of the magnetic field created by the separator rotor. Therefore, magnetized materials are repelled and automatically ejected out of the conveyor belt.
ECS separators can effectively divide the separated material into three fractions:
- Ferromagnetic metals
- Non-ferrous metals (such as aluminum, copper, brass,...)
- Non-conductive materials (plastics, wood, glass, etc.)
Eddy current separators are often used in waste recycling and in industrial processes where it is necessary to separate ferrous (and also non-ferrous) metal particles from non-conductive materials like plastics, glass or wood.
The advantage of eddy current separators lies in their high efficiency and speed - that is why they are ideal for high processing capacity requirements. Eddy current separators are very efficient tools for recycling and processing metal materials.
It should be emphasized that ECS separators do not serve to separate ferrous particles. In fact, for their proper functioning and especially in applications with high ferrous content, it is necessary to remove ferrous particles before the material is treated by the ECS (e. g., by installing a conventional magnetic separator in front of the ECS separator). Possible sporadic ferromagnetic particles can be captured by the ECS separator.
Concentric or eccentric eddy current separators?
We produce separators of non-ferrous metals in two variants. They differ in the rotor position and the number of magnetic poles:
- Separators with concentric magnetic rotors (ECS-C RAM)
These separators are intended for the separation of larger metal pieces (from 50 mm). Therefore, they are suitable for the treatment of e. g. municipal waste. Their biggest advantages lie in the low price and high processing capacity. The rotor comprises 4 magnetic poles.
- Separators with eccentric magnetic rotors (ECS-E BULL)
Thanks to their design, these devices enable to induce a strong magnetic field and are thus suitable for the separation of even very small metal particles (from 5 mm). They find their application e. g. in the e-waste separation. In case of our eddy current separators the rotor position can be changed while the separator is running, i. e.,the magnetic separator can be immediately adjusted to the currently processed material. This allows us to achieve the best possible separation results. The rotor comprises 12 magnetic poles.
We pride ourselves on producing ECS separators at an attractive price, without any compromise on quality at the same time.We thoroughly test and check all products to make sure they meet our strict quality standards. In this way, we can guarantee our customers that they get excellent quality for their money and a reliable, efficient device, sustainable in the long term.

- Automation: the eddy current separator can be easily integrated into automated processes and enables faster and more efficient sorting of materials.
- High processing capacity: the eddy current separator can process large amounts of materials in a short time and that is why it is ideal for industrial applications.
- Wide application options: eddy current separator is used in various industries such as waste sorting, metal sorting and recycling in general.
Each device requires maintenance. We are aware of the need to minimize the time required for the maintenance. That is why we make our ECS separators in such a way that the conveyor belt and the magnetic rotor shell (= a non-metallic drum) can be changed easily and very quickly. The time required to change the belt and rotor shell is in the order of minutes. The replacement procedure is very simple - even a separator operator can carry it out. Thus, there is no need for a service engineer intervention and the service costs can be reduced.
Separation module with a separating splitter
The key to a good separator function is the correct setting of the splitter blade that divides as accurately as possible the separated materials from each other. That is why we cared for the correct function and easy operation of this blade. The position of the splitter can be adjusted in two axes (i. e., horizontally as well as vertically) and its angle can be set too. In this way the separator can be easily adapted to fine-grained materials in order to achieve the best possible separation results.
The separator can also be equipped with an additional splitter, placed at the bottom of the separation module. The application of this splitter is needed if 100 % purity of the separated materials (i. e., the non-ferrous metals and the non-conductive materials) is required. The main splitter is to be adjusted in such a way that the separated non-ferrous metals are completely free of any non-conductive material. At the same time, we set the additional splitter so that the non-conductive material does not contain non-ferrous metals. As a result of this procedure you will get two absolutely clean materials and a material residue (= non-conductive material containing a small quantity of non-ferrous metals), which can be afterwards again separated.
Eddy current separator efficiency:
We carefully test the efficiency of every separator produced. We also test the ability of eddy current separators to separate non-ferrous metals. For testing we use aluminum and brass test pieces sized 20 x 20, 10 x 10 and 5 x 5 mm.
The ECS-E separator is able to separate all test pieces sized from 5 x 5 mm (both aluminium and brass).
Videos from these tests can be found in the section ‘Separation tests’.
We take pride in the fact that our products perfectly meet your needs. That is why we suggest that we will test (free of charge) customer materials by our separators. And according to the results of these tests, we will then design the most suitable device.
Conditions to ensure the correct functionality of the non-ferrous metal separator
Owing to the fact that the outreach of magnetic field at this type of separator is rather short, the distribution of the lowest layer of the material on the conveyor belt of the separator has to be taken into cosideration. And it is in such a way so that the height of the material being on the conveyor corresponds to the material size approximately and creates a monolithic mono-layer. The material should fall preferably in the loosened condition on the conveyor. All of this can be achieved e. g. by a vibration feeder or other special elements ensuring good spreading of the material on the conveyor.
In the case of the versions with the rotor embedded centrically there is a high risk of damage of the conveyor by a ferromagnetic particle caught by magnetic field of the rotor even also at the roller itself. That is why there is a need of noting rigorously separation of Fe particles before the entrance of the material on the conveyor belt especially at the centrical versions. Use magnetic drum, roller, plate or a combination of these to separate the unwanted metal particles

The eddy current separator ECS-E BULL uses an eccentric magnetic rotor, enabling the separation of very small pieces of non-ferrous metals.

Continuous rotor position adjustment with the separator running
The separated waste can have different properties (such as material sizes and types). The position of the eccentric rotor can be modified in order to achieve the best separation results. Our ECS-E BULL eddy current separator is unique as it allows to adjust the rotor position without interrupting the separator operation!As even in the course of the separation process the characteristics of the processed waste may change (there may be e. g. various material sizes and types on the conveyor belt), the sorting line operator must be able to react to this by changing the position of the separator rotor. Our separator allows for such an adjustment without being stopped, which reduces the downtime usually needed for this kind of adjustment.
