．． 5 fr/q) O pellet B (dimensions 3 throats φ x 3 circles density Q, 81r skin) is inserted and mixed, the pellets are rotated by the ribbon-shaped rotating blade 1, and the pellets z indicated by arrow P are inserted. Rise up the container peripheral wall surface in the direction of movement,
Thereafter, it descends downward toward the center of the interior as indicated by arrows Q and R. Its form is clearly seen in Figure 4. Due to the centrifugal force of the stirring blade 1, Z is shaped like a portex in which the peripheral wall is pushed up and the center settles, so that pellets with large particle sizes are , Benz) B with a small particle size easily rolls down the slope and collects in the center of the container 0 Therefore, a zone of Benz) B with a smaller particle size is created in the middle, creating a stagnation area with poor movement, making it impossible to mix uniformly. Met. Table 1 shows the results of measuring the concentration of pellets by sampling while discharging from the lower discharge port in order to measure the degree of mixing in the mixer in the above conventional example, and the standard deviation value σn
Table 1 (Problems to be Solved by the Invention) The present invention solves the drawbacks of the conventional vertical mixing device, and it A vertical mixing device that improves the mixing performance of powder and granules by guiding the pushed up powder to the center of the container and flattening the surface layer of the powder, thereby eliminating portex. □: Provide what you are trying to do.

在しなくなりペレットは均一に混合される。The inserted pellets z (mu, B) move up the peripheral wall surface as shown by the arrow p due to the rotation of the ribbon-type stirring blade 3, but are forcibly moved by the guide plate 6 on the surface layer as shown by the arrow Q'. Since the pellet is guided to the center of the shaft, the surface layer is flat without exhibiting a portex-like shape.Even pellets with different grain sizes move in the same way.There is no stagnant part where movement is slower than K. The pellets are mixed evenly.
