Abstract

The universal method of computation of specific hydraulic slope and critical rate during hydraulic transportation of polydisperse solid materials is suggested. This method enables to raise accuracy in calculations due to consideration of dependence of additional specific hydraulic slope caused by the presence of fine particles in hydraulic mixture and critical rate of pulp flow upon factor of hydraulic resistance.
