(Powder processing method)
A method for processing powder using the powder processing apparatus 1 described above will be exemplified below.
A predetermined amount of powder to be processed is introduced into the casing 2 from the raw material inlet 9. At this time, the filling amount (liter) of the powder is preferably 5% to 95% of the processing space 3 in the casing 2.

  Next, the rotor 5 is rotated at a predetermined rotation speed for a predetermined time, and the powder is stirred. The powder processing apparatus 1 is configured such that the rotational speed of the rotor 5 can be appropriately set and changed according to the type of powder.

  The flow of the powder at the time of stirring is shown in FIG. 1, FIG. 2, FIG. 4, and FIG. As shown by the arrow line in FIG. 2, the powder circulates in the rotation direction of the rotor 5. At this time, the powder rises by the ascending blade 8a and descends by the descending blade 8b. Therefore, as shown by the arrow line (dashed line) in FIG. Cycle in the direction. Actually, in the ascending blade 8a and the descending blade 8b, the powder can move along both the upper surface and the lower surface. Therefore, as shown in FIG. 11, the powder meanders up and down and circulates in the rotation direction of the rotor 5 while intersecting.

Therefore, the powder circulates in the vertical direction (vertical direction and / or direction close to vertical) in the casing 2.

  As described above, in the powder processing apparatus 1 according to the present embodiment, as shown in FIG. 11, the powder circulates along the rotation direction while meandering up and down, and at the same time, circulates in the vertical direction as well. A flow is generated. At this time, the macro level mixing is mainly performed by the vertical circulation, and the micro level precision mixing is mainly performed by the vertical meander circulation. As a result, the powder is subjected to a very strong stirring force as compared with conventional processing apparatuses, and even fine powders typified by nanometer size can be mixed accurately.

  Furthermore, according to the powder processing apparatus 1 according to the present embodiment, not only a precision mixing process in which powder particles are mixed in units of particles, but also a fine powder fusing process as a fusing process (compositing process), surface modification. Powder processing such as processing, surface smoothing processing, shape deformation processing, amorphization processing, and liquid addition mixing processing can be more reliably performed. In other words, the fine powder fusion process is a process for binding fine powder particles in the powder to particles having a larger diameter, and the surface modification process is a process for bonding a modifier to the surface of the powder particles. The powderizing process is a process for smoothing the surface of the powder particles, the shape change process is a process for changing the shape of the powder particles, and the amorphizing process is a process for changing the powder particles having a crystal structure into an amorphous state. The liquid mixing process is a process for changing the surface characteristics of the powder particles by chemical reaction with the powder particles, production of a powder particle surface layer, or the like. The powder that has undergone such processing is taken out from the product outlet 10.
