できる。First, when the powder 17 is charged, the center cap 5 is removed with the lid 2 and the cover 3 of the pot 1 attached to the pot 1 as shown in FIG. Next, as shown in FIG. 6B, the center cap 5 is attached and closed, the pot 1 is made horizontal, and the motor 21 is driven to rotate the pot 1. Thus, the powder is pulverized and mixed. When the powder 17 is taken out, as described above, the end of the center cap portion is pushed in, the fixing lever 9 is rotated, the gap 13 is opened between the lid 2 and the pot 1, and the lid fixing roller 8 is fixed. The engagement portion is engaged and the state is maintained. Next, open the on-off valve 12 of the powder outlet 11 to open the pot 1 in the same figure (c).
As shown by (4), it is tilted and rotated, and taken out to the powder receiver 51 arranged below. At this time, the powder 17 is contained in the lid 2 and the opening 15.
The powder 16 is taken out through the space covered with the cover 4 through the gap between and, but the balls 16 remain in the pot 1 and can be separated from each other because they are larger than the gap.

連作業を行うことが可能となる。As described above, according to the present invention, the powder can be loaded by removing the powder input port without pressing the lid of the pot, the sludge for powder separation, the powder receiver and the like, and the center cap portion is pushed in. As a result, the entire lid slides into the pot, and by rotating the pot, only the powder can be discharged from the gap between the lid and the opening of the pot. Therefore, a series of work time is significantly shortened, and the work that took 100 minutes in the conventional method can be done in 40 minutes, which is about 60%.
It was possible to reduce the work time. In addition, since there is no manual handling of heavy objects, it is possible to avoid falling and the like, and especially in nuclear material handling work, it is possible to improve safety by shortening the working time, and a small number of workers also perform a series of work It becomes possible to do.
