Nov 26 2001 in direct heat rotary dryers a hot gas flowing through the dryer provides the heat required for the vaporization of the water to promote gassolid contact most direct heat dryers have flights placed parallel along the length of the shell which lift solids and make them rain across the section of the dryer fig 1
Calculation of the quantity of water to be evaporated is explained below with a sample calculation if the throughput of the dryer is 60 kg of wet product per hour drying it from 55 moisture to 10 moisture the heat requirement is 60 kg of wet product contains 60 x 055 kg water 33 kg moisture and
Indirectly heated rotary dryers and calcinersare available for dusty finely divided materials and low to medium temperature calcining applications the rotary drum is partially enclosed and externally heated by a series of burners mounted in an insulated stationary chamber or jacket alternatively the products of combustion from an external
Principles of rotary drying the directly heated rotary dryer operates on the principle of lifting and showering the product through a hot gas stream moving either in parallel or counterflow whereas with the indirect dryer which is more suited to fine and dusty materials there is little or no contact between the product and the drying gases since they are heated from the outside via a
