ABSTRACT OF THE DISCLOSURE A first cylindrical drum member having an inlet portion for receiving materials to be treated, such as preheated coal and char includes a longitudinal axis and an outlet portion through which the treated materials are discharged into the inlet end por- tion of a second cylindrical drum member. The second drum member is independently supported for rotation relative to the first drum member and has a longitudinal axis coplanarly aligned with the longitudinal axis of the first drum member such that the drum mem- contraction of the drum members as they are subjected to different temperatures. The sealing assembly includes a running seal member that is secured to the periphery of the respective drum members and a static seal ring assembly that is movable positioned on the outer cylindrical surface of an annular support member that sur- rounds the respective drum members. A plurality of piston cylinder assemblies surround the annular support member, and each includes a piston rod arranged in abutting relation with the static seal ring assembly to maintain the seal ring assembly in sealing relation with the running seal upon longitudinal movement of the first drum member.
