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
