摘要

A rotary kiln for producing an expanded clay product from clay or clay slate, the kiln having a lining provided with ribs. These ribs are built of refractory bricks partly reinforced. Each brick is preferably constituted by two portions, one of which is provided with reinforcing bars extending within and protruding from said portion. The protruding bars serve as guide for the second brick portion during the securing of the two brick portions to each other. The advantage of such a rib construction is that it allows an easy and cheap restoration of the rib when part of the rib is worn down without simultaneously necessitating a replacement of the lining.
