Most systems in the cement industry work with low oxygen levels. They can take air with 3% oxygen from the preconsigner and feed it to the mill, which normally has an inert atmosphere. Things can go wrong because the oxygen concentration can drop and suddenly go up, and as soon as it becomes more than 12 or 13%, an explosive atmosphere starts.

The cement industry is wonderful with the latest techniques, and using the dry methods and helping automatic systems, has witnessed tremendous advances in the 160 year history of manufacturing its own. Some of the cement production process like Alumina Cement, entirely is different from Production method of Portland cement.

The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation. Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110ºC – 120ºC, cooling to below 80ºC is necessary to avoid this reaction.
