Cement ball mill grinding. The bulk density of steel balls is generally 7.85 tons/m3, and that of ceramic balls is 3.6 tons/m3. The volume of the ball mill is usually calculated by multiplying the inner diameter of the mill by its length. The percentage of the mill volume occupied by the media is typically between 40% and 50%.

The ball mill grinds the clinker and the raw material mixing them well to manufacture cement. The final discharge from the mill is fed into a bucket elevator, which takes the material to a separator. Here the material is separated into a fine product, which is sent to concrete silos for storage and subsequent packaging.
