ABSTRACT:
A seal for the ends of a rotary kiln or similar rotary device having a plurality of graphite blocks adapted to conform to the circular periphery of the kiln exterior. The graphite blocks are pressed gently against the shell by seal adjusting segments radially biased toward the center of rotation of the kiln. The seal adjusting segments are adjustably supported in a holder with a counterweighted rope circumscribing the seal adjusting segments to provide the biasing pressure and thereby hold the graphite blocks in sealing engagement with the kiln.
