Continuous Mixing of Solids

Abstract

Powder mixing is common in many industrial processes, yet traditional methods of investigation provide only very limited information on the influence of agitator geometry and important operational parameters on flow patterns. In this work, a particular technique called Positron Emission Particle Tracking (PEPT) is used to investigate powder flow patterns within a continuous mixer. The motion of a single positron‐emitting particle is followed and the technique yields spatial coordinates of this tracer as a function of time.
