  • METHOD TO REDUCE BUILD-UPS, CRUSTS AND RING FORMATION IN CLINKER PRODUCTION
    Publication number: 20190153347
    Abstract: Some embodiments are directed to a method to avoid the negative effect of both sulphur and vanadium presence contained in solid fuel used in cement clinker manufacturing line (build-up, kiln rings, etc.). Some embodiments are methods to prepare, dose and use a fuel additive based on an alkaline earth metal to allow the combination of vanadium and sulphur with said added alkaline earth metal, so that corrosion, build-up, crusts and ring formation in cement pre-heaters and kilns due to the presence of those components are avoided.

  • Method for producing a clinker for hydraulic cement with low COemission and high resistance
    Patent number: 8715411
    Abstract: A method for producing a clinker for cement, comprising grinding a raw flour comprising, especially, Al2O3, Fe2O3 and SO3 in contents such that the formula for calculating SO3 content of=0.261×Al2O3?0.638×Fe2O3+k, where 2.5<k<3.5, then by sintering flour in an overn wherein the temperature is between 1250° C. and 1350° C. and oxygen content is between 2.5% and 10% by volume.
