Abstract
Provided is an indirectly heating rotary dryer which has achieved enhanced energy-saving performance by reducing heating tubes non-contacting with material to be dried and reducing power required for rotation even when a hold up ratio is increased. Specifically provided is an indirectly heating rotary dryer having four partition wallsextended respectively along an shaft center C in an inner space of a rotating shellat angle intervals of 90 degrees in the vertical and horizontal directions. The four partition wallspartition the inner space of the rotating shellat a lateral section of the rotating shellinto four approximately-sector-shaped small spaces K respectively extended along the shaft center C. Heating tubesare aligned in the rotating shellin three lines extended respectively in parallel to the shaft center C of the rotating shell. The heat tubesheat and dry the material H to be dried by supplying heated steam to the heating tubesand performing heat exchange with the material H to be dried in the rotating shell
