As in a rotary dryer, typical bed loading in kilns is about 10%. As one might expect, the direct-fired rotary dryer acting as a dispersion device can achieve higher heat transfer rates than refractory lined kilns. The result is that the rotary dryer can transfer more heat per unit volume than a rotary kiln. Indirect Rotary Dryers & Rotary Kilns

The working principle of rotary drum dryers involves the transfer of heat to the material being dried. The process begins by feeding the wet material into the dryer through the feed chute. As the drum rotates, the lifting flights pick up the material and drop it through the hot air stream. This continuous movement exposes the material to the ...
