Abstract

A grate cooler arranged at right angles to a rotary kiln and having its vertical longitudinal central plane spaced a distance between 10 and 150 cm from the discharge end of the rotary kiln. The zone of the grate cooler lying below the material discharge end of the rotary kiln has more stationary grating plates and more unventilated grating plates per unit area than the laterally adjacent zones of the material receiving end and in the remaining region of the cooler. This results in good protection of the grating plates at the material receiving end and an even distribution of the material over the whole width of the cooler by means of a distribution cone which is kept in motion.
