ABSTRACT OF THE DISCLSOURE: In a rotary kiln, bulk material is first moved in a countercurrent to hot gases in that portion which adjoins the feed end and is dried and, if desired, precalcined by a direct heat exchange. The succeeding portion of the rotary kiln contains an inserted body, which is disposed in the calcining zone and defines an annulus with the shell of the rotary kiln. The dried bulk material is fed to that annulus and is calcined by an indirect heat exchange mainly on the surface of the inserted body. Hot gases art fed into the inserted body and flow from it into the rotary kiln.
