At the outlet of the fixed container 1, a separation annular plate 2 is fixedly mounted. In the ring, a rotating disk 4 fixed to the tip of a drive shaft 3 has an outer peripheral surface and the inside of the separation annular plate 2. It is rotatably arranged while keeping a slight gap A between itself and the peripheral surface uniform over the entire circumference. With this small gap A, the outflow of the grinding aid is stopped, and only the suspension is continuously extracted.
The extracted suspension is commercialized as a certain kind of emulsion or coating agent.

[0006] In recent years, with the advancement of technology in the field of using such a suspension, the demand for the size of the dispersant in the suspension has been changing year by year. For example, in a conventional general-purpose suspension, the particle size of the dispersant was about 2 μm to 3 μm, but at present, the fine particle “3 μm to 0.7 μm” and the ultrafine particle “0.
7 μm or less ”, the area of micronization of the dispersant has been almost divided according to the field of use of the suspension.

By the way, the dispersant in such a suspension is not always fine from the beginning, but is trapped between the media in the above-mentioned fixed container and pulverized by stirring to be fine. The finer the particles of the medium used for this, the smaller the particle size of the product (suspension) (particle size of the dispersant). In addition, the size is reduced to some extent according to the number of processes (from injection into the fixed container to extraction from the outlet).

FIG. 4 is a characteristic diagram showing the correlation between the particle size of the product and the size of the medium contained in the fixed stirring container. This figure shows a characteristic curve for each particle diameter of the medium, in which the horizontal axis indicates the number of treatments and the vertical axis indicates the particle diameter of the product. The above characteristic curve is 1.0 to 1.5 mmφ, 0.8 to
1.25mmφ, 0.5-0.8mmφ, 0.42-
The graph shows the particle size reduction characteristics when a medium having a particle diameter of 0.6 mmφ and 0.35 to 0.59 mmφ is used.

For example, the relationship between the medium particle size and the product particle size when the number of times of processing is one is roughly, but roughly:
In order to obtain a product having a particle size of 0 μmφ, 1.0 to 1.5 mm
It is preferable to use a medium having a diameter of 0.8 to 1.25 mmφ to obtain a product having a particle diameter of 1.6 μmφ.
A medium of 0.5 to 0.8 mmφ to a product particle size of 2 μmφ,
Medium of 0.42 to 0.6 mmφ for product particle size of 1.0 μmφ, and 0.35 to 0.5 for product particle size of 0.9 μmφ
It turns out that it is better to use each medium of 9 mmφ.

When the number of times of processing is set to two, using the same medium, 1.5 μmφ, 1.2 μmφ,
It can be seen that products having particle diameters of 0.85 μmφ, 0.75 μmφ and 0.68 μmφ can be obtained. In any case, it is found that the product particle diameter converges to a constant value from the time when the number of treatments exceeds four, and that the miniaturization does not proceed. Therefore, the product particle sizes 0.91 μmφ, 0.77 μmφ, 0.57
μmφ, 0.52 μmφ and 0.44 μmφ can be seen as indicating the minimum product particle size corresponding to each of the above media.

From the above, it is assumed that a medium of 0.5 mmφ is used and the number of times of processing is two (three or more times have a problem in terms of a reduction in processing efficiency and an increase in cost) (see the bottom of FIG. 4). It can be seen that a product particle size of 0.7 μmφ can be obtained. The product particle size of 0.7 μmφ belongs to the region of ultrafine particles.

Since the above-mentioned medium is worn, it must be replaced when the medium has been worn to some extent. If this replacement is neglected, there occurs a problem that the medium forms a nodule so as to close the gap at the outlet of the apparatus (see the gap A in FIG. 3) and hinders the extraction of the suspension. 0.7μmφ, which is the area of the ultrafine particles, which has been demanded in recent years
In order to obtain a product having a particle size of 0.5 mm, a medium having a diameter of 0.5 mm is usually supplied, and when the medium is worn down to 0.3 mm, the medium is replaced with a new medium having a diameter of 0.5 mm.

On the other hand, it has been empirically found that the gap A at the outlet of the apparatus is preferably not more than 1/3 of the medium particle size in order to efficiently separate the medium during the suspension extraction. Therefore, as described above, a medium having a diameter of 0.5 mm
When used until the media is worn down, the gap A at the outlet of the apparatus shown in FIG.
It is configured to form a gap of 1/3 of 0.3 mmφ, ie, 0.1 mm, corresponding to φ.

However, at present, in order to meet the demands for miniaturization and power saving of various OA devices, the particle size of products is further increased due to ink ribbons, filters, special papers and the like incorporated or used in these OA devices. There is a demand for miniaturization. As described above (see FIG. 4), the particle size of the medium must be reduced in order to efficiently reduce the product particle size. For example, a medium of 0.3 mmφ finer than the above-mentioned 0.5 mmφ is initially supplied, and when this medium is worn down to 0.2 mmφ, it must be replaced with a new medium. Then, the gap A at the apparatus outlet corresponds to 0.2 mmφ of the worn medium particle diameter immediately before replacement,
It must be configured to form a gap of 1/3, that is, 0.07 mm.

However, according to the current technology, no matter how precisely the separation annular plate 2 and the rotary disk 4 are formed, a certain degree of variation occurs in the mounting of the rotary disk 4 to the drive shaft 3. Cannot be avoided, and the eccentricity cannot be completely removed from the rotation of the drive shaft 3. Therefore, it is extremely difficult to rotate the rotating disk 4 while maintaining a gap of 0.07 mm from the inner peripheral surface of the separation annular plate 2. There was no way to cope with the problem other than increasing the number of times of processing using a relatively large medium. However, this causes a problem that not only the processing efficiency is reduced but also the processing cost is significantly increased, and the dissatisfaction is large, and some improvement has been desired.
