In the cement manufacturing process large fans draw air through the kiln, precalciner, mills and filters to an ex-haust stack. Many smaller fans push the air into the grate cooler to reduce the temperature of the hot clinker leaving the kiln 1. All these airflows have to be adjusted and controlled as atmospheric conditions, process con-

It is clearly helpful, therefore, if the clinker is cool as it enters the mill. From an environmental and a cost viewpoint, the cooler reduces energy consumption by extracting heat from the clinker, enabling it to be used to heat the raw materials. From a cement performance viewpoint, faster cooling of the clinker enhances silicate reactivity.
