。However, there has come to be a demand for a more finely pulverized product than that obtained by the pulverizer presented in the actual it@5q-x3xczI issue. Moreover, there was a demand for pulverizing materials that are difficult to pulverize using conventional pulverizers and the pulverizer of Utility Model Application No. 131911/1980 using a simple device. Furthermore, you can save three things at the same time: cost, time, and space. There was an extremely strong demand for a pulverizer that could produce the desired fine powder in just one pass without the need for a classifier.

する微粉砕機に在する。"Means for Solving the Problem" The gist of the present invention to achieve the above object is to install a drive shaft on the left and right sides of a cylindrical body having a raw material supply port and a product suction port on the left and right sides. On one side, an outer rotary plate with a large number of stirring plates installed on the tip of the outer circumferential part is fixed, and on the other side of the drive shaft, a large number of stirring plates are installed on the tip of the outer circumference that fit into the stirring plates of the outer rotating plate. The inner rotary plate provided is fixed, and the two rotary plates are fitted together, and the outer rotary plate and the inner rotary plate are rotated in forward and reverse directions, and a liner is placed on the inner surface of the cylinder facing the outer rotary plate. The product suction port is connected to the suction machine, and the air sucked from the raw material supply port passes through the crushing body formed by the outer rotary plate and the inner rotary plate and is sucked from the product suction port. The present invention is a pulverizer characterized by the following:

In other words, the material to be crushed that collides with the agitation plate of the outer rotary plate is repelled by the agitation plate and collides with the liner, and at the same time, the protrusions on the liner (the shape of these protrusions are serrated and file-like) This shape is determined by the properties of the material to be crushed and the required fineness.

ある。This finely divided material further collides with the outer rotary plate and is crushed, and at the same time, it is thrown off toward the liner and crushed. After this repetition, the material that has been pulverized to some extent is pulled by the suction air and moved toward the product suction port. However, since there is an inner rotary plate in the middle, the particles are blown away by the stirring plate of this rotary plate, collide with the lower part of the outer rotary plate, and are further pulverized. Here, the rotation directions of the outer rotary plate and the inner rotary plate are in a positive or reverse relationship, that is, for example, when the outer rotary plate rotates clockwise, the inner rotary plate rotates counterclockwise. The speed at which the stirring plates of one car's rotating plate pass each other (
Their relative speed) doubles, they collide with stronger force (velocity), and this collision is repeated, turning them into ultra-fine particles. The material to be crushed, which has been ultra-finely pulverized in this manner, is pulled by the suction force of the product suction port, and is taken out and collected from the suction port.

The material to be crushed is thrown toward the liner 4 by the centrifugal force of the rotating stirring plate 34, and is ground into a tooth shape or crushed. The crushed material to be crushed is scattered toward the stirring plate 34, collides with the stirring plate 34 again, is crushed, and is again flung toward the liner 4, where it is shaved or crushed into the tooth shape of the liner. The material to be pulverized undergoes this action repeatedly, and when it undergoes a certain phase change and becomes pulverized, it is pulled by the suction air and moves towards the product suction port 6. However, since the inner rotating plate 32 is present in the middle, the stirring plate 34 of the outer rotating plate 31 receives the centrifugal force of the stirring plate 37 of this rotating plate 32.
It is flipped downward and collides with the lower part of the stirring plate 34. Here, the outer rotating plate 31 and the inner rotating plate 32
Since the direction of rotation is positive and reverse, one image pressure plate 34°370 passes each other at speed (relative speed is doubled, and collides with stronger force (velocity W). The collision between the plates 34 and 37 is repeated and the material is ultra-finely pulverized.The thus ultra-finely pulverized material is sucked together with air from the product suction port 6 and collected in a collection section (bag filter, etc.). .

This figure shows an example in which a rasp pattern) is engraved. however,
This tooth profile may or may not be provided as described above, and its shape is determined depending on the properties of the object to be crushed and the size of the crushed particles.

の内側回転板３２を通過することができる作用。In addition, as mentioned above, the inner rotating plate 32 is the outer rotating plate 31.
The material to be crushed is pulverized between the pulverized material and the material to be pulverized that does not reach the desired particle size (those whose volume is larger than the pulverized material is flicked away toward the outer rotary plate 31 until the desired particle size is achieved. In other words, only particles having a desired particle size can pass through the inner rotary plate 32.

所望粒度の微粉を入手することができる。In other words, it has been found that this inner rotary plate 32 also performs the function of classifying particles to determine whether or not they have a desired particle size. Since the inner rotary plate 32 has a classification function in this way, it is not necessary to provide a separate classifier in the non-inventive pulverizer, and fine powder of a desired particle size can be reliably obtained.
