<p>Grate plate for the high temp. zone of a grate cooler, esp. for the cooling of cement clinker, where the metal body of the plate is made of boxes, open at the top, the bases of the boxes being provided with openings for the passage of the air used for cooling. The novelty is the use of a ceramic layer in the boxes, the layer being either homogeneous, or assembled from bricks, and also provided with air holes. The metal body may consist of one large box fitted on the underside with fixing elements, or it may be only partly box-shaped, and, in the latter case, the box may be above or below the plane of the plate. Provides lower mfg. cost and longer working life.</p> |
