[0002] Magnetic separation equipment is one of the most widely used and highly versatile models in the industry. It is suitable for the separation of substances with magnetic differences. At present, in the chemical industry, ceramics, glass raw materials, refractory materials, plastics and other industries, it is necessary to use The magnetic separation equipment used to remove iron powder from dry fine powder mainly includes dry powder vibration type and drum type: the former is that the material enters the magnetic board box from the funnel, and falls vertically through the magnetic induction rod under the action of gravity. During the process, the ferromagnetic substance in the material is absorbed by the magnetic induction rod. When the absorbed ferromagnetic substance accumulates a lot, it is necessary to manually transfer the magnetic field to remove the iron. Not only is the operation troublesome, the efficiency is low, and the iron removal effect is poor; Falling on the rotating drum, the non-ferromagnetic material in it falls directly into the discharge hopper, the ferromagnetic material is attracted by the magnetic field on the surface of the drum and rotates with the drum, when it rotates to the non-magnetic field area, the ferromagnetic material falls under the action of gravity In the iron collecting box, although the iron remover is easy to operate, the effective adsorption time of ferromagnetic substances is short, the number of flips on the drum is small, the phenomenon of magnetic wrapping and magnetic agglomeration is serious, and it is difficult to achieve the expected effect of magnetic separation. The iron ore selected by the two methods is of low grade and low selection ratio. Therefore, we propose a dry powder magnetic separation equipment
