Cement Production | Apache Cement | Shwe Taung Cement Co, Ltd, The heated raw meal now enters the kiln where the gas temperature exceeds 2000 °C, where it is transformed into a molten mixture inside the rotating kiln At the temperature of 1450 °C the minerals in the raw meal undergo chemical reaction to form a new compound known as Clinker, which is the pre-curser for the production of cementThe cement kiln, From a cement performance viewpoint, faster cooling of the clinker enhances silicate reactivity The cooled clinker is then conveyed either to the clinker store or directly to the clinker mill The clinker store is usually capable of holding several weeks' supply of clinker, so that deliveries to customers can be maintained when the kiln is not ,Modern Processing Techniques to minimize cost in Cement ,, meal, cement and minerals, whereas Cemax Mill is mainly for cement grinding The mill can be used for pre-grinding and finish grinding This mill-system claims to have advantages of ball mill, roller mill and roller press in terms of reliability and energy savings The energy saving is claimed to beCement mill, A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cementMost cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills
