。For example, fine metal particles recovered from various types of slag and dust, shot that has been left for a certain period of time, etc. have oxides and other substances attached to their surfaces, so it is necessary to remove the surface deposits. There are two ways to remove the surface layer: one is to chemically elute the surface layer, and the other is to physically grind it. However, the former method requires complicated selection of treatment liquid and post-treatment of the treatment waste liquid, and also requires chemical processing. Problems remain in the post-processing of the treated material surface, and the latter
At present, most conventional techniques are unable to effectively remove the adhering surface layer when it comes to fine particles of less than mm.
本発明は上記現状を艦み、非常に微細な対象物であって

We aim to provide a device that can
The gist is that inside a storage container consisting of a cylindrical body with an opening at the top,
A rotating vertical shaft is inserted and arranged, a required number of plate-shaped rotating blades are arranged around the rotating vertical shaft, and a large number of magnetically sensitive media are charged into the storage container, and the bottom of the storage container is A device for grinding and cleaning fine metal particles, characterized in that an electromagnet is disposed on the outside, a cleaning liquid supply port is provided at the lower part of the side wall of the storage container, and an overflow port is provided at the upper opening. It is.

By rotating at high speed, the fine metal particles M are rotated at high speed while being attached to the optical surface of the magnetically sensitive medium (4). Therefore, the fine metals collide with each other with a stronger collision force than when only the fine metal particles M collide, that is, the collision is stronger due to the added weight of the media (4), and the surface of the fine metal particles M The surface adhesion layer F of oxides and the like adhering to the surface is peeled off and removed. This grinding may be carried out in a dry manner or may be carried out in a wet manner in which water or necessary oil is interposed as much as possible to achieve an appropriate pulp concentration.

If it is used alone, the energy for grinding generated is small even if they impact each other at high speed because of the lack of heavy weight, but since it is rotated at high speed together with media that has a certain weight, it rotates at high speed together with the media. K causes strong collisions between the media and the inner wall of the storage container while adhering to the surface of the media.K is an oxide that is strongly attached to the surface of fine metal particles and generates enough energy for grinding. It is possible to easily peel off surface deposits such as. Using the apparatus of the present invention, the recovered material (coarse particle dust) from converter dust having the particle size distribution and chemical composition shown in Tables 1 and 2 below is ground, and then an electromagnet (7
) is cleaned in an energized state, and this is used as a metal iron grade of approximately 95, which is sufficient to be used as a mixed material for removing material from a converter.
Table 3 below shows the treatment time required to improve the quality to weight % R (-Fe, the yield in that case, and the results of a similar treatment using a conventional apparatus for comparison.
