Flow Structure of Bead Mills with a Centrifugal System for Separating Beads from a Crushed Suspension

Abstract

The results of studies of the flow structure of a horizontal bead mill with a centrifugal system for separating bead particles from a ground suspension are presented. Diffusion, cellular, and recirculation flow-structure models are used to describe the residence time of the dispersed material in the bead mill. To determine the parameters of these models, F-response curves are used, which are obtained by the stepwise perturbation method under various operating conditions of the mill. As a result of the research, it is established that the structure of the flows of bead mills of this design is best described by the recirculation model.
