Abstract
The spark tracing method and high speed photography have been used to investigate the flow conditions inside a cross stream air classifier. The photographs obtained clearly demonstrated the increasing mutual interplay between gas flow and particle stream with increasing concentration of the solids. The results show that, in general, in fluid-solids systems the method can be used up to volume concentrations of about 1×10−2.
