ABSTRACT:
An arrangement for mounting a cooling cowl on the discharge end of a rotary kiln which allows for radial and axial differential expansion between kiln and cowl. The cowl is mounted on the kiln contiguous the kiln discharge end, with the cowl being positioned radially outwardly of the outer peripheral surface of the kiln to define an annulus between the inner peripheral surface of the cowl and the outer peripheral surface of the kiln through which cooling air can flow. A radially outer set of end castings is supported by the kiln at the discharge end and defines an axial end closure for the annulus. A radially inner set of end castings is supported by the kiln at the discharge end and retains the "nose brick" of the kiln lining. Both the radially outer and the radially inner end castings are supported by the kiln so as to be structurally independent of the cowl. A plurality of spacer bars made of a flexible material such as steel is positioned in the annulus, the bars extending in a direction substantially parallel to the axis of rotation of the kiln and being angularly spaced apart, the respective bars being fixedly secured at one end thereof only to the cowl and at the opposite end thereof only to the kiln. A pair of keeper blocks, preferably supported by the cowl, are positioned contiguous opposite circumferentially spaced sides of a given spacer bar whereby to substantially prevent circumferential shifting of the cowl.
