raw material propotioning and grinding process

MANUFACTURING OF CEMENT Raw materials used

Grinding . Process . The crushed raw materials are fed in to a ball mill and a little water is added . The steel balls in the ball mill pulverized the raw material which form a slurry with water . The slurry is passed through storage tanks where the proportioning of compound is adjusted to ensure desired chemical composition .

Raw material grinding has the objective of producing a homogeneous raw meal with a fineness requirement (less than 10 to 15% residue on the 90-μm sieve) from a raw material containing moisture (3 to 8%) with a feed particle size of 100–200 mm. Usually, silos after the grinding mill are used for a final homogenisation of the raw meal.
