Abstract

A model was proposed for determining the efficiency of fractional separation in a uniflow cyclone. The model includes parameters that characterize the motion of a particle in the cyclone and, hence, the degree of separation, namely, the distance that the particle travels when moving in a helical path, and this path itself. The separation efficiency in a uniflow cyclone of a new design was experimentally studied. The experiments were carried out with quartz flour of four particle size fractions: 15, 20, 30, and 50 μm. The efficiency of the cyclone in the separation of small particles was high for apparatuses of this type. The separation efficiency curves were analyzed.
