When a cylinder rotating around horizontal axis was put on the turntable rotating around vertical axis, and when a device to trim the powder attached to the cylinder wall was added, wheat flour and aluminum powder could be stirred well. But starch and aluminum powder could not be stirred well with that way. It was found that they could be stirred well, if the axis of the cylinder was set apart from the horizontal axis of rotation with distance of several mm.
