Contact2013-6-9 and alumina. Finished cement is produced by finely grinding together around 95% cement clinker with 5% gypsum (or anhydrite) which helps to retard the setting time of the cement. The quality of cement clinker is directly related to the chemistry of the raw materials used. Around 80–90% of raw material for the kiln feed is limestone.
ContactRaw mill is also called cement raw mill, similar to cement ball mill, it is an important cement milling equipment used in the cement production process. Raw mill is mainly used for grinding cement raw meal in the cement factory production process. It is also suitable for metallurgical, chemical, electric power and other industrial mining enterprises to grind various ores and other grindable
