Results of experimental studies of the hydrodynamics 
of two-chamber vortex dryers are presented. Empirical relations are 
obtained for determining the critical velocity of gas outflow and 
the retentivity of an apparatus as a function of the operating and 
design parameters and the properties of the disperse material. It 
is found that the hydraulic resistance of the developed dryers does 
not depend on the properties of the treated material and is proportional 
to the square of the gas flow rate. Relations for calculation of the 
coefficients of hydraulic resistance for apparatuses not loaded and 
loaded with material are obtained.
