after cooling, the clinker may be stored temporarily in a clinker store, or it may pass directly to the cement mill. the cement mill grinds the clinker to a fine powder. a small amount of gypsum - a form of calcium sulfate - is normally ground up with the clinker. the gypsum controls the setting properties of the cement when water is added.
grinding is an abrasive machining process that uses a grinding wheel or grinder as the cutting tool. grinding is a subset of cutting, as grinding is a true metal-cutting process. grinding is very common in mineral processing plants and the cement industry. grinding is used to finish workpieces that must show high surface quality and high
