emf- PERMagROLL

New generation of magnetic separators, designed by emf, combines the latest technological achievements in magnetic concentration based on High-intensity, High grade; high power RE- permanent magnets generate an exceptionally high magnetic gradient for the most cost-effective way to process weakly magnetic materials. Optimal separation of the material is achieved by custom design and any number of roll concentrator modules may be used to attain the required throughput or separation.

Dry granules of the material are fed onto short conveyor belts of thin yet durable material passing over rolls of customized magnetic configuration. The non-magnetic particles fall freely off the end of the roll while the magnetic particles adhere momentarily to the roll and are discharged into a separate chute by means of an adjustable splitter below the belt. The modular nature of the emf-PERMagROLL enables any number of units to be stacked to achieve the required performance.

Since the material is never in contact with the magnetic roll there is no wear on the magnets and under normal conditions magnetic strength is retained indefinitely.
