Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

On the basis of the kinematic model of entrainment of small particles by large ones the abnormally nonmonotonic dependence of the separation curve on the particle size is explained. The influence of the particle density, the classifier length, the split-parameter, and the average size of particles on the depth of the “fish-hook” effect has been investigated.
