"Firing" in cement industry parlance is the supply of heat to a kiln by use of a burning fuel. Throughout the early history of the industry, fuel was added to static kilns in lump form, pretty much in its "as-received" state. With the advent of the rotary kiln, it was necessary to develop sophisticated means of preparing the fuel and injecting it into the kiln system.
Clinker is a critical component in the production of cement and forms the intermediate product during the cement manufacturing process. It can be best described as a nodular material, usually grayish …
would be a length of 13.5 m and a diameter of 2.5 m, with a speed of approximately 20 revolutions per minute. Such a mill would normally have a load of approximately 90 tons of grinding media, graduated from 90 mm to 60 mm in the first chamber, 50 mm to 15 mm in the second chamber and 15 mm down in the final chamber.
Dry process cement kiln: the dry process cement kiln is much more thermally efficient than the wet process cement kiln. This is because raw meal prepared for the dry process is dry powder with a water content of less than 1%, which reduces the amount of heat needed to evaporate water.
