Title:
ROTATING DEVICE, AND METHOD FOR MANUFACTURING FINE PARTICLES
Document Type and Number:
WIPO Patent Application WO/2022/075473
Kind Code:
A1
Abstract:
According to the present invention, crushing is performed using a rotating device (ball mill) in which a container can be caused to rotate in three dimensions (two-axis rotation). The rotating device includes a main driving disk (6), a driven disk (9), and a transmission mechanism (10). The transmission mechanism (10) converts drive rotation about the X-axis into container rotation about the Z-axis. An object to be crushed and hard balls are placed in a spherical container (22). The device has a reversing mechanism, and switches between forward rotation and reverse rotation as appropriate. The effect of the invention is exhibited in particular if the size of the fine particles after crushing is small (for example, at most equal to 1/100 of the size of the hard balls).
