Abstract: To provide a crystallizer to generate pseudo non-gravity environment by three-dimensional high speed rotation and to minimize influence of gravity in crystallization process for crystallizing a substance from a solution. The crystallizer has turning gear, container 9, and container supporting unit 30. The turning gear includes horizontal shafts 3,6, first rotation frame 1 coupled to first shafts, motor 4 rotating frame 1 about X-X line, vertical shafts 7,8 provided on frame 1, and driving force transmission system 10. System 10 includes first disc 11 and second disc 12. First disc 11 rotates relative to frame 1 about axis of shafts 6. Second disc 12 is coupled to shaft 7. Contact between disc 11 and disc 12 transmits a turning force of frame 1 rotated by motor 4 to cause frame 2 to rotate about Y-Y line.

Abstract: A planetary ball mill includes: a revolution turning arm turned about a revolution shaft rotated by a driving force; mill pots each supported on the revolution turning arm so as to be rotated about a rotation shaft inclined from the vertical direction toward the side of the revolution shaft; and an outer circumferential pot receiver which is disposed fixedly on the upper side of the revolution turning arm along the whole part of a circumference around the revolution shaft and with which the outer peripheral surfaces of the mill pots revolving attendantly on the turning of the revolution turning arm make contact, whereby the mill pots are put into rotation.
