1. Increase the exposed area of the material: The material is ground by the ball mill to ensure that the raw material is fully chemically reacted in the kiln, so that the combustion can be fully completed, the cement is completely hydrated, and high strength is produced. In order to achieve the above effects, the fineness of the cement raw meal should be controlled at 0.08 mm, the sieve residue of the square hole sieve should be 10% or less, the cement should be controlled below 8%, and the coal powder should be controlled below 14%.

2. Mix all kinds of materials evenly: limestone, clay and iron powder in cement raw materials, slag, gypsum and clinker in cement can not only be crushed after being ground by ball mill, but also can be mixed evenly to ensure The quality of the cement.https://www.wuxiorient.com/
