Abstract
In order to create a grate plate design for a thrust grating cooler for cooling hot material such as, for example, cement clinker, this grate plate design has troughs at its upper side for accepting and retaining cool material for the purpose of protecting the grate plate against thermal overload, whereby these troughs are to be supplied with cooling air via cooling air channels arranged therebetween and via air exit slots without the risk of blockage thereof. A grate plate is provided wherein a plurality of cooling air channels that extend up to the upper side of the grate plates and limit the troughs from one another are arranged in the grate plate member parallel to the longitudinal axis of the grate plates, and whereby the partitions between the air channels and the troughs comprise air exit slots proceeding parallel to the longitudinal axis of the plates which are arranged immediately above the bottom plate of the grate plate.
