Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an apparatus for pulverizing a pulverized material by applying rolling motion to conductive particles K11 using a moving magnetic field. The method of pulverizing the pulverized material is described in the Bulletin of Japanese Patent Publication No. 51-5991, which is shown in No. 115. In the tlX1 diagram, 1 is a reaction vessel, 2 is a ferromagnetic particle, 3 is a rotating electromagnetic field inductor, 4 is a crank, and 5 is a connecting rod. According to this device 1&C, the pulverized material to be pulverized is inserted into the reaction vessel 1, and the crank 4. Reaction volume eI via connecting rod 5
& When moving through a rotating electromagnetic field, the ferromagnetic particles 2 in the reaction vessel 1 rotate violently and can pulverize the pulverized material.

However, the pulverized material in the reaction container 1 accumulates in the lower part of the reaction container 1 due to its own weight, and pulverization is performed only in the lower part 1 of the reaction container. Therefore, the upper side of the reaction vessel 1 is useless for pulverization, and the energy of the rotating electromagnetic field inductor cannot be used effectively.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an apparatus that can eliminate the drawbacks of conventional devices, can effectively utilize the energy input for crushing, and can crush the entire area of a container containing the crushed material to be crushed. Our goal is to provide the following.

Next, one embodiment of the present invention will be described in detail based on the drawings.

FIG. 2 shows an embodiment of the present invention, in which a flat plate type moving magnetic field generating device 11 is arranged at the lower part 11, and an arc-shaped moving magnetic field generating device is arranged at the upper side, and between these moving magnetic field generating devices, the upper side A container 13 containing conductive particles 14 is arranged in the container 13 . The moving directions Cσ and d of the moving magnetic fields of the forward moving magnetic field generators 11 and 12 are set to be opposite directions, respectively. By arranging the moving magnetic field generators 11 and 12 so as to face each other and making the moving directions of their respective moving magnetic fields in opposite directions, the effect of the moving magnetic fields of the moving magnetic field generators 11 and 12 can be reduced to the electrical conductivity inside the container 13. Particles of 14 K can be effectively applied. Furthermore, since the moving magnetic field generators 12 are shaped like an arc, the magnetic field strength in the space between the moving magnetic field generators 11.12 differs at each point, for example, the center of the moving magnetic field generators 11.12. Just as there is a difference in the distance between the moving magnetic field generators, there is also a difference in magnetic field strength between the X-X section near the section and the Y-Y section near the end. Then, the magnetic field Y(v
-y). Therefore, the electromagnetic force proportional to the magnetic field strength acts on the conductive particles 14 K in each magnetic field, causing a difference in crushing force, and in the Y-Y cross section, X-XFr
Since the electric field is stronger than in the surface area, the movement and activity of the conductive particles is more powerful and the pulverization is carried out. By varying the electric field strength in this way, for example, by providing partitions as shown by dotted lines inside the container 13, hard pulverized material can be pulverized at both ends of the container, and soft pulverized material can be pulverized in the center. I can do it.

The third factor shows another embodiment of the present invention, and the difference from FIG. The inner arc diameter of the iron core is smaller than that of the moving magnetic field generator 16 on the side. The container 18 is manufactured to match the arc of each moving magnetic field generator. As a result, there is a difference in magnetic field strength between the X, -X1 cross section and the Y□-Yl cross section, and the magnetic field strength is greater at the YI Y0 cross section. In addition, the bottom of the container is Yl-Y, and the cross-section is on the lower side than the Xl-X1 cross-section, so pulverized material with a large specific gravity or heavy pulverized material will migrate to the Y, -Y, cross-section side. .

This has the advantage that pulverized materials with large specific gravity or heavy pulverized materials can be more powerfully pulverized near the Yl-Y□ cross section, where the magnetic field strength is large and the pulverizing force is large. Although only pulverization has been described, the apparatus of the present invention can utilize a mixed VC% of liquid and powder.

As explained above, according to the present invention, one or both of the moving magnetic field generators are shaped like an arc so that the distance between the opposing moving magnetic field generators is not uniform, and the distribution of magnetic field strength is varied. The energy of the moving magnetic field generator can be used effectively, and the magnetic field can be crushed evenly within the container. Since the motion of the conductive particles is more complicated than that of electric field strength of , it has the advantage that the pulverization efficiency can be improved.
