Rührtechnologische Forschung zum Suspendieren und Dispergieren

Abstract

This article deals with the suspension in a stirred tank and the behavior of sinking and floating particles. It is shown that a single-baffle configuration and an up-pumping axial impeller are optimal devices for floating particles. The experimental results for the analysis of particle strain and breakage in turbulent dispersions demonstrate that at the same specific power input, the stirrer with the lowest tip-speed creates the largest droplets (equal to lowest particle strain).
