Abstract

The present invention relates to a method of and apparatus for cooling a material, such as lime, treated in a rotary tubular kiln, in a cooler associated with the kiln. The cooler comprises at least one chamber, into the inlet of which hot material treated in the kiln drops from the kiln via a chute/chutes connecting the kiln and said chamber and forms a material bed in the lowermost portion of said chamber, and the material flows further countercurrently in relation to the cooling gas flow, discharging from the outlet end of the chamber. Material is circulated in the inlet end of the cooling chamber and material is returned thereto so that the material being circulated and the material being returned form at the position of the chute/chutes said layer, onto which the fresh hot material dropping from the kiln continuously forms a new bed and is mixed with the material being circulated and the material being returned.
