Abstract

A rotatable drum arrangement, wherein the drum is mounted on support rings such that circumferential expansion and contraction of the drum relative to said support rings does not adversely affect the mounting. In a preferred embodiment, drum blocks are mounted to the drum, and corresponding ring blocks are mounted to the support ring. The side surfaces of adjacent drum blocks and ring blocks support the weight of the drum on the ring. In this arrangement, gaps may be maintained between the drum and support ring that allow for expansion and contraction of the drum. In the preferred embodiment, there is also a drive sprocket mounted on the drum with a sprocket mounting arrangement that also accommodates expansion and contraction of the drum.
