Abstract
The service life of grate plates for pusher grate coolers for the cooling of hot cement clinker, and the like, is greatly increased at low cost by providing a replaceable wearing part (21) at the forward plate end pushing edge of the grate plate body (12). The wear life of the overlap region of the surface of the grate plate is enhanced by special treatment or coating.
