role of raw mill in cement plant

  • A Review On Environmental and Health Impacts Of Cement ...

    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 passed through the end of the rotary Kiln.
