Jun 27, 2021 In the dry process, raw materials are also ground finely in a mill, but no water is added and the feed enters the kiln in a dry state. Therefore, much less fuel is needed in the kiln. Many older kilns use the wet process in the past, wet grinding and mixing technologies provided uniform and consistent material mixing, resulting in a.

History Of Raw Mill From Ancient To Modern Of Cement

This paper mainly introduces the raw mill in cement plant. In order to achieve the desired setting qualities in the finished product, a quantity (2-8 , but typically 5 ) of calcium sulfate (usually gypsum or anhydrite) is added to the clinker and the mixture is finely ground to form the finished cement powder. This is achieved in a cement raw mill.
