クリーム状になったりして媒体による被処理物の分散効
果を阻害することがあった。When dispersing a material to be processed such as powder using a media dispersion machine, the material to be processed is pre-dispersed using a stirrer such as a Disilver before being applied to the media dispersion machine. Because it is a formula, workability is poor and efficiency is not good.Furthermore, in addition to the air contained in the powder due to adhesion or adsorption, air is further drawn into the processed material during the preliminary dispersion process. As a result, during the powder dispersion process of the method, air, etc. adheres to or adsorbs between the workpiece and the grinding medium, and these air, etc. are further dispersed, and the medium becomes like a soft cream. In some cases, the dispersion effect of the material to be treated may be inhibited.

The present invention relates to a method and apparatus in which the material to be treated is pulverized by the movement of the pulverizing medium and continuously discharged from an outlet provided at the bottom of the container.

Φが形成されている。In the figure, the material to be processed such as powder and the liquid are supplied to the powder quantitative supply device (2) via a quantitative supply device such as a liquid quantitative supply pump (3), respectively, through a supply port (1) formed at the top of the container (1). 4) and (5) into the container.The container can be formed into various shapes and structures, and the lid (
6) is formed with an exhaust port (7), which is connected to a reduced pressure source if desired. A rotary shaft (8) connected to a driving means is provided in the container, and a rotary blade (9) is attached to the rotary shaft so as to give a floating and upward movement to a grinding medium (not shown) housed in the container. This is provided. In the figure,
The rotary blade uses a paddle type blade inclined at approximately ≠j degrees, but a screw type or other suitable blade may also be used. Fixed blades αq are provided on the inner wall of the container, and the fixed blades are also inclined so as to float and raise the grinding medium. The diameter, rotation speed, etc. of the rotary blades and the like are appropriately determined depending on the properties of the medium and the object to be processed. A screen is provided at the bottom of the container to separate the grinding medium,
A discharge port αυ is formed below it, a quantitative discharge device M(2) is connected to the discharge port, and the disperser side is connected to the tip of the quantitative discharge device. The quantitative discharge device is connected to the quantitative supply device via an appropriate control means so as to control the quantitative supply device so that the liquid level in the container is substantially constant. Around the container, there are heating, cooling, etc.
Φ is formed.

される。Therefore, the powder supplied in a fixed amount along with the liquid to the container is
It adheres to the grinding medium that is given movement such as floating, rising, and swirling by the rotary blades in the container, and is fragmented and dispersed into fine powder by the thrusting action and impact action between the grinding media. . Further, while the grinding medium moves up and down, gas such as air contained in the powder separates from the powder and rises,
Exhaust from the exhaust port. At this time, the powder and liquid that are continuously supplied from above the container tend to cause the grinding medium to move downwards in the container, but as mentioned above, the rotating blades provide floating motion. There is no risk of concentration at the bottom of the container. While staying in the container for a predetermined time,
The above-mentioned powder is finely divided into fine powders, dispersed in a liquid at a desired degree of dispersion, and continuously and quantitatively discharged from a discharge port in the form of a slurry.
取り出された処理物中には、従来のような空気等の混入
はなく、次の媒体分散工程での分散効率を高めることが
できる。Unlike the conventional method, air and the like are not mixed into the processed material taken out, and the dispersion efficiency in the next medium dispersion step can be improved.
