A New Particle Size Distribution Apparatus based on Unbalance by Centrifugal Sedimentation

Abstract

A new apparatus for the measurement of particle size distribution based on the unbalance caused by centrifugal sedimentation was made on an experimental bases. The size distributions obtained by this method with a constant revolution of the rotor were compared with those measured by other methods using the same sample.
Furthermore, in order to shorten the measuring time and expand the measuring size range, some additional attempts were conducted with a linear acceleration followed by a constant revolution of the rotor. They gave similar results of size distribution to the measurements at a constant revolution.
