Grinding apparatus for grinding an out-of-round trunnion or tire for a rotary kiln

摘要

The present invention relates to a grinding apparatus for grinding an out-of-round trunnion tire for a rotating kiln. The present invention is mounted on a trunnion roller such that a tracking wheel and a grinder are in tangent with the out-of-round trunnion tire. The mounting bracket supports a means for angling the grinder so that it is in tangent with the out-of-round tire and making it round. The grinder is part of a grinder head assembly which is mounted on the angling means. The grinder head assembly includes the grinder, a housing and a drive mechanism. The drive mechanism includes a motor which drives the grinder wheel so that it grinds the trunnion tire back into round.
