HEAT AND MASS TRANSFER IN THE DRYING OF
DISPERSE MATERIALS IN COCURRENT DRUM DRIERS

UDC 539.215.4

Heat and mass transfer which accompanies the process of 
drying of disperse materials in cocurrent drum driers has been studied. 
The results of modeling of moisture removal from dried disperse material 
under the effect of a temperature field with account for the hydrodynamic 
situation in the drum drier allow one to run the process with minimum 
deviations of the final humidity and temperature of particles from 
specified values. A system of control over the drum driers, which 
considerably decreases the consumption of energy carriers and improves 
the efficiency of the equipment used, has been developed and implemented.
