Maximum recovery of recyclable materials – IMRO Maschinenbau – Europe's sorting and conveying experts
IMRO Eddy current separators combine all-important features to achieve reliable and efficient separation of non-ferrous metals:
High-tech IMRO RCSX D eccentric rotor advantages:
• 40 magnetic poles comprising the strongest magnets
• Ultra-large diameter on inductor pole drum
• The highest magnetic strength
• 1.27 kHz polar alternation frequency
Ferrous parts do not become attracted to areas extending beyond the magnetic field/zone.
Other manufacturers use:
• 38 or fewer magnetic poles
• Smaller magnetic pole drum diameters
To prevent ferrous particles from melting the belt and the drum shell, other manufacturers use concentric rotors which can include a drum shell containing a ceramic-based lining. This type of drum shell greatly reduces both magnetic strength and separation power by increasing the gap between the material flow and the magnets.
Ferrous particles are attracted to and pulled along with the pole drum. As a result, this causes high wear and tear to the drum shell.
In the IMRO eccentric rotor system, the trajectory is enhanced by adjusting the effective range of the magnetic pole drum between 0 and 20 degrees.
The infinitely variable pole drum is set between 0 to 20 degrees during operation, optimising separation performance of the machine significantly.
In a concentric rotor, non-ferrous particles are attracted by the magnetic field far too early in the process, preventing optimal separation.
Here neither the effective range of the magnetic field, nor the trajectory of the non-ferrous particles can be influenced in such a system. Particularly for the separation of copper wires and heavy metals the capability of adjusting the effective magnetic range is required.
IMRO Patent: The pole drum is infinitely adjustable between 0 and 20 degrees during operation. Optionally, an electronic control device for adjusting for the IMRO magnet system, as well as the separating vertex, can also be delivered.
