Method of making liner sections for rotary pulverizers

摘要

A sectional liner for use on the interior of a ball mill liner or rotary pulverizer. The sectional liner has a rubber base that is undulating or sinuate in contour. Means are provided in the rubber base to facilitate the securing of the base to the shell of a ball mill. The rubber base may or may not be covered with a layer of fiberglass which in turn is covered with an exterior surface of polyurethane. Ceramic tiles are embedded in the polyurethane being aligned in rows with a clearance space between the tiles filled with polurethane. The ceramic tiles, polyurethane, and rubber are all bonded together during the cure cycle to form a one piece replaceable sectional liner for ball mills.
