The essential characteristic of a grate cooler is a layer of clinker spread on a more-or-less horizontal perforated grate, through which cold air is blown. The grate is made of steel, and the cold air keeps it sufficiently cool to avoid melting or burning. The clinker progresses through the cooler by moving more-or-less horizontally along the grate, and so the direction of the cooling …
