ABSTRACT:
A rotary reactor is shown having an improved internal lining including a lifter section which extends along an interior surface of the reactor chamber for lifting material from a lower portion of the chamber to an upper portion thereof as the chamber rotates. The lifter section is formed as a monolithic casting of a refractory material having a polygonal cross-section which includes a series of blunt faces alternating with a series of slanted faces. The slanted faces are aligned with a direction of rotation of the reactor such that the slanted faces of the refractory material first contact the material being lifted.
