Cement Milling Understanding Cement

Cement milling is usually carried out using ball mills with two or more separate chambers containing different sizes of grinding media (steel balls). 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

CEMENT MANUFACTURING PROCESS LEARN TO

Grinding- The klinkers, so obtained from the rotary kiln, are ground to the required degree of fineness in a ball mill or a tube mill.During grinding, a small quantity of gypsum (about 3% to 4%) is added. Gypsum controls the initial setting time of cement. If gypsum is not added, the cement would set soon as water is added to it. thus, gypsum acts as a retarder, and delays the initial setting
