Interaction of рarticles of different size classes in the separation flows

At present, theoretical concepts of gravitational separation processes are mainly limited by the study of the interaction between a flow and a solitary particle. Then the main conclusions of this analysis are applied to a mass process. However, this analysis is absolutely insufficient, because some elementary phenomena such as the ingress of coarse particles into the fine product output and vice versa cannot be interpreted from its standpoint. It is also impossible to predict the results of the classification of a material with a specific granulometric composition on a specific apparatus on its basis. This article discusses o more complete model of the process. It is based on the behavior of a plurality of particles of different sizes. This made it possible to determine the probalitity of particles of different sizes in the separation flows. This is how on additional parameter is obtained in the general process model.
