The invention relates to an
eddy current loss-free
magnetic separator, which comprises a feed inlet equipped upper box, a lower box, a permanent magnetic cylinder, a material separator, and a
drive motor. The technical key points of the invention lie in that: the permanent magnetic cylinder is made of
glass fiber reinforced plastics, the bottom of the lower box is a W-shaped structure, two feet of the W-shaped structure are a tailing port and a concentrate port respectively, the permanent magnetic cylinder is disposed between the upper box and the lower box, and the lower part of the permanent magnetic cylinder is provided with the material separator between the tailing port and the concentrate port; a main shaft is limited in the permanent magnetic cylinder and is provided with a magnetic
system not rotating along with the permanent magnetic cylinder, the main shaft is provided with a fixation ring, the end of the permanent magnetic cylinder is mounted on the fixation ring, and the main shaft in the permanent magnetic cylinder is connected to the output shaft of the
drive motor; and the top of the upper box is provided with a distribution device corresponding to the feed inlet. The
magnetic separator provided by the invention solves the problems of short service life, easy equipment damage and the like caused by easy wear of cylinder
skin and cylinder heating in existing magnetic separators, and has the advantages of long service life, simple operation, large treatment capacity, small
power consumption, and low maintenance cost, etc.
