Abstract
A clinker cooler (3) comprises a plurality of grates (5) arranged in adjacent and overlapping relation to each other for conveying hot cement clinker (11) supplied from a kiln (1). The grate (5) is formed with an air hole (20) through which air from a fan (8) is jetted toward the cement clinker via a compartment (16) to cool the cement clinker. A distribution chamber (13) is equipped to a part of the grate corresponding to a part of cement clinker which is not cooled sufficiently, and the air from the fan (14) is jetted to such part of cement clinker which is not cooled sufficiently. The quantity of air jetted from the distribution chamber is adjusted by varying a degree of opening of a damper (15).
