ABSTRACT:
A rotary kiln assembly comprising an inlet arrangement, a rotary kiln and an outlet arrangement. A seal arrangement is provided between the inlet arrangement and the rotary kiln and a seal arrangement is provided between the rotary kiln and the outlet arrangement. It is a problem with rotary kiln assemblies to remove the seals without relative movement of the rotary kiln or the inlet or outlet arrangements. At least one of the seal arrangements is made retractable in telescopic manner and the kiln assembly includes detachable spacing means such that the retractable seal arrangement can be removed from the kiln assembly as a unit without fouling or movement of the kiln or the inlet or outlet arrangements and hence without disturbing their alignment. The spacer means may be detachable only after retraction of the sealing arrangement and may be integral with a part of the sealing arrangement.
