Abstract
A cooler for cooling hot particulate material which has been subjected to heat treatment in an industrial kiln such as a rotary kiln for manufacturing cement clinker, includes a grate for receiving and supporting hot material from the kiln, at least one cooling gas duct which is connected to slots in the grate for introducing cooling gases into the hot material and a compressed air system for injecting compressed air into the material on the grate. The cooler also comprises at least one flow restricting device provided in the cooling gas duct. Use of the one or more flow restricting devices may permit only a very limited amount of the compressed air that is injected into the material on the grate to pass through the cooling gas duct.
