A recording, photometric particle-size analyser has been developed which is useful for determining the particle-size distributions of powdered materials in the subsieve range. Provision for moving the optical system upwards and/or downwards continuously allows us rapid analysis for the silica particles, and the results obtained were compared with those obtained by the standard method, in which the optical system does not move. The measurements were carried out in 10 minutes by means of this apparatus for the finer particles, while the particles with larger density or with wider distribution could be analysed more accurate by than by usual method by moving the optical system downwards and by stopping it during the measurements. It was ascertained that the movement of the optical system has no effect on the results obtained.
