Luzheng Chen, Dahe Xiong, in Progress in Filtration and Separation, 2015. 2.2.2 Disc and Roll Magnetic Separators. In the past, cross-belt and rotating disc high-intensity magnetic separators were used for concentration of relatively coarse weakly magnetic particles such as wolframite and ilmenite, etc., under dry conditions.In the operation of these two magnetic separators, material is ...


The induced roll magnetic separator achieves separation by exploiting magnetic properties of the material it is processing, no matter how feeble it may be. However, due to the high intensities involved in the operation of this series of induced rolls, it is essential that highly magnetic material be removed prior to treatment by the main rolls.


MasterMag Induced Roll Magnetic Separators are applied in extraction and concentration purification of a wide range of minerals. chemicals and metallics. Separation is achieved by exploiting the magnetic properties Of the material, however feeble. Provided the material is …


Induced Magnetic Roll Separator 3 After adjustment has been set, the locking bolts should be securely tightened. Nonmagnetic gauges (brass, copper, etc.) can be used to determine the gap between the pole nose and the roll. This gap should be gauged with the magnet turned on as the gap decreases slightly with the magnet on.
