Internal Recycled Particles Circulation in Vortex Granulator

Аннотация

A theoretical model that describes the internal recycled particles separation process in suspended-layer vortex granulators (SLVG) with a height-variable cross-sectional area is presented. Relationships are derived to determine the recycled particles circulation time in SLVG with a specified configuration. The calculated results are confirmed by experimental studies on an SLVG prototype. The results of the analytical solution of the equations of the mathematical model can be used to design SLVG with an internal recycled particles circulation, which can be organized in various ways, depending on the need for simple recirculation or the presence of additional recycled particles thermal treatment stage during recirculation.
