Studies on a Shaking Separator (III)

Motion of a Grain on the Plane

Abstract

Succeeding to the previous report, this paper dealt minutely with the theoretical analysis and experimental studies concerning the flowing velocity of a grain in the condition of three dimensional movement on the plane surface on a shaking separator with a sinusoidal motion. And the motion of a grain was experimentally studied with the pictures of stroboscope. The mean velocity of a grain was the value in the flowing direction of it.
The main results were as follows;
1) The motion of a grain was subject to the frequencies, inclination angles (α, β), projection angles, amplitudes of the shaking separator and frictional coefficient of a grain.
2) The mean negative velocity in the little frictional coefficient of a grain gradually increased with the increase of frequencies and inclination angles.
3) The mean velocity of a grain of the theoretical value was nearly equal to that of the experimental value. And the rationality of the theoretical analysis was ascertained.
