Eddy Current Separator ECS / Non-ferrous metals separators

Easy maintenance

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.

Automatic lubrication of bearings

The bearings and housing of the magnetic rotor are lubricated by an automatic lubrication system controlled by a PLC. Easy setting of the lubrication interval or lubrication interruption by a PLC, e. g. when the separator is switched off or the line is shut down. If the lubricant level drops below the recommended level, a light signal directly on the lubrication cartridge as well as in the control system notifies the operator to replace the lubrication cartridge (that is commonly available).

The bearings of the driven belt pulley are maintenance-free under normal operating conditions. They can be relubricated by standard lubricants if necessary.

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 1 x 1 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 main advantages of the eddy current separator with a concentric rotor are the attractive price and the high capacity.

The main advantages of the eddy current separator with an eccentric magnetic rotor are the separation of very small non-ferrous particles and the possible adjustment of the rotor position while the separator is running. This allows us to change continuously the separator settings and achieve the best separation results.
