Manufacturing Of Cement Mixing of raw material(wet or dry) Burning Grinding 7. Wet process- when raw materials are soft. Raw materials are mixed and crushed, stored in silos. Crushed material from different silos are drawn in appropriate proportion in a channel called wet grinding mill. Mixed with water called slurry.A raw mill is the equipment used to grind raw materials into "raw mix during the manufacture of cement. Dry raw mills are the normal technology installed today, allowing minimization of energy consumption and CO2 emissions. Process of raw mill in grinding of raw material and silo storage 1. Transporting crushed raw material to raw mill

A Raw Mill is the equipment used to grind raw materials into "rawmix" during the manufacture of cement. Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement mill. The Rawmilling stage of the process effectively defines the chemistry (and therefore physicalwet process, or the semidry process [10]. In a dry cement manufacturing process, dry raw mix contains less than 20% moisture by mass. However, in a wet process water is added to the raw mix to form slurry and then is transported to the kiln [11]. Raw meal or blended raw materials are fed into the upper end of the pre-heater tower and then ...

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. Clayey raw material accounts for between 10–15%, although the precise amounts will vary. Magnesium carbonate, which may be present in limestone, is the main undesirable impurity.
