ABSTRACT:
An apparatus is disclosed for securing a two component lining to the inside shell of a rotary kiln or the like. The apparatus includes a plurality of standoffs each having a bottom portion for connection to the inside shell of the kiln, a middle portion, and a top portion. A grid is connected to each of the top portions by means of a weld. A layer of a lightweight first castable material having high insulative properties is gunned or cast along the inside shell of the kiln to a depth less than the height of the standoffs. A second castable material having abrasion resistive properties is gunned or cast onto the surface of the first castable material at a depth substantially level with the surface of the grid. The standoffs serve as an anchor to secure the two layers of castible material into position . The grid connected to the top portion of the standoffs is preferably a honeycomb grid which aids the second castable material in protecting the first castable material from damage due to abrasion.
