Eddy current loss-free magnetic separator

Abstract

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.

Description

technical field [0001] The invention relates to mineral processing equipment, in particular to a high-efficiency, energy-saving and large-capacity magnetic separator without eddy current loss. Background technique [0002] The permanent magnetic dry separator has the characteristics of simple structure, low operating cost, large-particle mineral separation, energy saving and environmental protection, and is widely used in the mineral processing industry. However, the average lifespan of ordinary dry separators is 3 to 6 years. Under harsh working conditions, some products have a lifespan of less than a few months, and the wear and heating of the barrel skin are the main causes of failure. The wear of the shell is mainly caused by the sliding between the iron ore particles and the shell. Once the shell is broken, the ore particles will enter the shell and be adsorbed on the surface of the magnetic system, resulting in the lock of the shell. If the ore enters the bearing, it ...
