処理済原料の排出作業に移ることになる。The raw material feeding operation is continued until the upper surface of the raw material held in the rotary kiln reaches the vicinity of the openings provided at both ends of the cylindrical body. During this time, the raw material is also stirred and heat exchanged with an externally supplied heat source, but the full-scale processing work is started again by the tilting means 19 after the raw material has been input.
This is done by operating the outer cylinder 11 to fix and hold the outer cylinder 11 in a substantially horizontal state and to continuously rotate the outer cylinder 11. In this way, when the initial processing target is reached, the tilting means 19 is operated again while the rotary kiln is rotating, and the outer cylinder 1
1. That is, the cylindrical body 1 is tilted to a predetermined angle, preferably a tilt angle set to a larger angle than when the raw material is introduced,
The process will now move on to the discharge of processed raw materials.

である等、極めてコンパクトなものと成し得る。As can be seen from the above-described embodiments, the present invention includes a pair of trunnion shafts protruding from approximately the center of an outer cylinder arranged concentrically and spaced apart from the cylindrical body of a rotary kiln. The outer cylinder is rotatably supported by a bearing, and the outer cylinder is equipped with means for supporting the rotation of the cylindrical body, and a tilting means is mounted at a position apart from the trunnion shaft, and the end face of the outer cylinder is attached to the cylindrical body. By forming an arc shape with the trunnion shaft as a rotation radius on the same or inside end surface of the body, and equipping a charging side hood and a discharge side hood corresponding to the end surface of the outer cylinder, it is possible to The internal holding capacity of the rotary kiln, that is, the processing capacity and the discharge capacity, can be dramatically improved.In addition, in terms of equipment configuration, the length of the rotary kiln is much shorter than that of conventional rotary kilns. Since the trunnion shaft is located approximately in the center of the rotary kiln, it is possible to increase the tilt angle and quickly operate the rotary kiln. The sealing means between the two is simple and can be extremely compact.
