WebThe optimum separation (grade) is also obtained at a pulp density of 25%. Generally, the separation inside the trough is governed by the layer of particles flows over the surface along with the hindered settling phenomena which enhances the separation based on the settling ratio of the heavy and light density particles. Webunder hindered settling conditions are typically confined to several tens of data points. The aim of this paper is to develop a new empirical equation for hindered settling of non-cohesive particles that expands the commonly used equation of Richardson and Zaki (1954a) by integrating 53 studies and 548 data sets from a wide range of disciplines.
