Kiln process in cement manufacturing

Dec 22, 2021

Nov 30, 2019 Mixing of raw materials: The processes used for the manufacture of portland cement can be classified as dry and wet. In dry process. The raw materials are first reduced in size of about 25mm in crushers and Crushed material is ground to get fine particles into ball mill or tube mill. Each material after screening is stored in a separate hopper

    Manufacturing process of Cement The production process for cement consists of drying, grinding and mixing limestone and additives like bauxite and iron ore into a powder known as “raw meal”. The raw meal is then heated and burned in a pre-heater and kiln and then cooled in an air cooling system to form a semi-finished product, known as a clinker

    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
