Optimization of Construction of the Mixing Chamber with a Multiple Jets Inlet of a Heat Carrier in Pneumatic Conveying Dryers for Potassium Chloride

Abstract

Results are presented for physical and mathematical modeling of the operation of different mixing chambers with a multiple jets inlet of a heat carrier in pneumatic conveying driers for potassium chloride. The influence of the shape of the chamber and the spacing of holes for heat carrier input on temperature inhomogeneity of the resulting mixture, particulates temperature and contact intensity of particulates with the chamber walls are considered. A mixing chamber design providing minimal contact intensity and sticking of the dryable particulates with the walls is recommended.
