• The effect of gravitation on the partial separation efficiency of a cascade impactor has been neglected in the past. However, most industrial dusts contain relatively large particles for which the gravitational force should be taken into account. In this work, a gravitational term is introduced into the equation of particle motion, the resultant theoretical separation efficiency being in good agreement with the experimental results. Consequently, the model appears to represent adequately the separation mechanism of a cascade impactor affected by particle gravity. A method of particle size analysis using a cascade impactor with the gravitational effect is proposed.
