How Cement is Made | Lafarge Exshaw

The raw feed enters the cool end of the kiln, gradually passes down to the hot end, then descends out of the kiln and cools down. The material formed in the kiln is called 'clinker'. After cooling, the clinker may be stored temporarily in the clinker storage hall, or it may pass directly to the cement mill, which grinds the clinker to a fine powder. A small amount of gypsum is ground up ...
