Five major advantages of using alumina ceramic dry grinding material instead of high chromium steel balls for cement grinding.
① Energy saving and consumption reducing: With a loading capacity of 60% of steel balls, the current of the main machine of the mill is reduced by more than 20%; More than 15% of electricity is saved per ton of cement.
② Quality improvement: Improve grinding efficiency; Improve cement performance; More reasonable particle size distribution; Improved sphericity of particles; Cement has good adaptability to concrete admixtures.
③ Cooling and noise reduction: the temperature inside the mill is reduced by more than 20 ℃; Reduced mill noise.
④ Wear resistance: The ball wear of microcrystalline high-strength wear-resistant ceramic abrasive is 50% of that of steel balls.
⑤ Environmental Protection: The use of microcrystalline high-strength wear-resistant ceramic grinding bodies is beneficial for achieving green production.
