Abstract
When a cylinder rotating around horizontal axis was put on the turntable rotating around vertical axis, liquids of high viscosity in the cylinder were stirred well with the effects of Coriolis force. In this paper, we tried to stir powder and powder with Coriolis force. When a device to trim the powder attached to the cylinder wall was added, it was found possible to stir powder and powder with Coriolis force. A computer program was developed to catch the positions of particle from a photograph of powder and small particles, for example, mixture of wheat flour and aluminum powder. And a method to evaluate the uniformity of mixture was established. Then the better conditions to stir powder and powder were studied. As a result, they were stirred well when a ratio of the rotation number of cylinder and that of turntable was a certain value.
