Sep 01, 2018· Water added during cement industry in three stages which are cooling clinker, grinding and during mixing water for making concrete. Most previous studies concerned only with mixing water. Almost the water used as mixing for making concrete should be pure as natural water that is drinkable and has no odor or pronounced taste.

Clinker and gypsum, being mixed together in predetermined proportions, are fed to the grinding mills. Chemical gypsum, if used instead of natural gypsum, needs to be dried either by natural sun drying or by mechanical drying, before it is used with cooled and dried clinker for inter grinding in mills.

Grinding clinker requires a lot of energy. How easy a particular clinker is to grind ("grindability") is not always easy to predict, but large clusters of belite due to coarse silica in the feed are difficult to grind. Rapid cooling of the clinker is thought to improve grindability due to the presence of microcracks in alite and to the finer

Oct 22, 2016· CLINKER GRINDING. Clinker, the discharge product from the kiln, is partially cooled and broken or crushed to about ¾” 1″ as feed to finish mills. Fineness of grind is dependent upon the type of cement to be produced. Since fineness of grind falls below standard screen size accuracy, fineness of grind is determined by use of a “Wagner

During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the “setting of cement”. If not added, the cement will set immediately after mixing of water leaving no time for concrete placing.
