Document Type and Number:
WIPO Patent Application WO/2019/187909

A1
Abstract:
This rotary kiln is provided with: a barrel 10 that accommodates an object to be processed and can rotate around an axis; a heating means 11 for heating the object; and a supply means 12 for supplying the object into the barrel from an inlet provided on one end side of the barrel. A plurality of helical parts 20, standing from the inner circumferential surface of the barrel to a height lower than the inner radius and extending in a spiral shape in an axial direction of the barrel, are disposed at intervals inside the barrel, and flight plates 21 that are for stirring the object and stand from the inner circumferential surface of the barrel are disposed between the plurality of helical parts. The helical parts extend in a spiral shape in the direction in which the object flows toward the inlet due to forward rotation of the barrel, and a spiral path formed by the helical parts extending in the spiral shape is configured to be open rather than closed from one end to the other end thereof.
