を目的とする。2. Description of the Related Art Conventionally, when a self-curing material is kneaded by the above-described twin-screw kneading apparatus, there has been a problem that the kneaded material adheres to the kneading blades and hardens, thereby deteriorating the kneading effect. To solve this problem, an apparatus having a self-cleaning effect is known from Japanese Patent Publication No. 62-44969. However, even with this known device, it is not possible to sufficiently scrape off the deposits on the kneading blades.
In short, the smaller the rotation ratio integer (N) of the two rotating shafts, the greater (poor) the degree of approach of the mixing blades, and conversely, the larger the rotation ratio integer (N), the smaller the degree of approach of the kneading blades ( Better) and the degree of scraping increased, but it was limited. That is, it was found that when the rotation ratio integer (N) was set to 7, the phase slightly shifted, and the kneading blades collided at some point. The present invention has been made in view of the above problems, and in order to enhance the self-cleaning effect of the kneading blades of the twin-screw kneading apparatus, the rotation ratio integer values of the two rotating shafts are increased and the kneading blades collide with each other. It is an object of the present invention to provide a twin-screw kneading device that does not match.

するところは著大である。According to the present invention, as is apparent from the above description, the rotational ratio of the two rotating shafts arranged side by side in the twin-screw kneader is provided at an unequal speed of 6: 7, and the rotating shaft speed is low. The kneading blades provided on the rotating shaft are attached at 90-degree pitch intervals along the circumferential screw line of the rotating shaft, and the kneading blades provided on the rotating shaft having a high rotation speed are 105 along the circumferential screw line of the rotating shaft. The pitch is set at a pitch interval, so the degree of closeness between the kneading blades is small and the self-cleaning effect of scraping off the deposits adhering to the kneading blades is large, eliminating the need for post-work deposit removal work and kneading. There are various effects, such as the fact that the kneading performance at the time is not reduced, and the advantage is remarkable.
