In abroad, Canada’s A.S. Mujumdar [2] and others have studied roto-louver dryer. Roller dryer is another type of rotary dryer, in which the horizontal drum is equipped with longitudinal shutters, forming a conical drum in the external drum. The hot air passes through the shutters and liquefies at the bottom of the inner cylinder.

Based on the structure of a traditional rotary dryer, steam tube rotary dryer calcinator is equipped with some steam heating tubes inside of the dryer. The heating tubes run through the dryer with pattern of 1 to 5 concentric circle(s), supplying heat needed by drying process. The heating tubes rotate along with the rotary drum.
