Cohesive fine particles are handled in the process of various industrial fields such as photocatalyst, particle coating, cosmetic powder, granulator, drying, and secondary battery. Agglomerates are formed and exhibit different properties from individual particles. Therefore, in the process using fine particles, it is important to stir and defoaming before performing the process so that the fine particles do not form aggregated particles.

Conventionally, as such a powder mixing device, it is configured to be rotatable around an orbital axis, a table provided with an autorotation axis, and a sample can be accommodated, and is installed on the table and installed on the rotation axis It is known that a container capable of rotating around and revolving according to rotation around the revolution axis of a table is provided, and the axis of revolution is inclined at a predetermined angle so as to intersect with the revolution axis (see Patent Document 1 below).

This powder mixing device is capable of defoaming the sample in the container by revolving the container around the revolution axis, and also rotating the container around the revolution axis while rotating the container around the revolution axis as a stirring and defoaming method around the rotation axis inclined to intersect the revolution axis By rotating with the furnace, the sample in the container can be stirred and defoamed, and various samples can be stirred and defoamed in a short time.

On the other hand, with such a powder mixing device, even if the container containing the sample is rotated while revolving, the sample in the container is not mixed well and remains at a predetermined location in the container (for example, a location near the rotation axis of the bottom of the container). , stirring may become insufficient, and there is room for improvement. In addition, in the process of handling fine particles as samples, problems such as attachment of fine particles to the container and formation of dust occur, resulting in a large amount of loss of fine particles, lowering productivity, and contamination of the device for long-term use The problem was that it was difficult to do.

Accordingly, various studies are being conducted on a powder mixing device that can be stirred and defoamed more efficiently to improve the productivity of fine particles, can be applied to various particle sizes and types, and has improved durability.
