the clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. as the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. it can now be considered portland cement. the cement is so fine it will easily pass through.cement manufacturing - components of a cement plant,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. the basic components of the cement production process..history of cement,a few years later, in 1845, isaac johnson made the first modern portland cement by firing a mixture of chalk and clay at much higher temperatures, similar to those used today. at these temperatures (1400c-1500c), clinkering occurs and minerals form which are very reactive and more strongly cementitious..cement production: raw meal production in steps,and this quality is achieved during cement production with exactly matched process steps. in the first stage, the raw meal is produced, as described below. schenck process measuring and feeding devices play a major role in this process. 1. raw material production.
