MAGNETIC SEPARATOR AND CARRIER FOR ELECTROPHOTOGRAPHY MAGNETICALLY-SEPARATED BY THE MAGNETIC SEPARATOR

摘要

PROBLEM TO BE SOLVED: To provide a magnetic separator which is capable of conducting the precise separation not only in case where a powder material including a magnetic material and non-magnetic material of which the magnetic characteristics has a big difference but also in case where a powder material including a strong magnetic material and a weak magnetic material of which the magnetic characteristics has not a big difference, and in case where the separation is conducted by means of the threshold value.;SOLUTION: In the magnetic separator having at least a hollow cylindrical tube comprised of a non-magnetic material, a magnetic pole generating member arranged in the hollow cylindrical tube, a driving part to rotate the hollow cylindrical tube, a holding part to fix and hold the magnetic pole generating member, a supply part to supply the powder material to the surface of the hollow cylindrical tube and a recovery part to recover the powder material, it is characterized in that a plurality of hollow cylindrical tubes are equipped and arranged so that the hollow cylindrical tubes are in proximity and neighbored with each other, and in that the powder material is transferred between the hollow cylindrical tubes arranged in proximity to reach the recovery part. It is preferable that the powder material is transferred with vibration.;COPYRIGHT: (C)2009,JPO&INPIT
