Abstract
Disclosed is a high efficiency catalyst for cement, which comprises rare earth ores 5-10%, sulfur iron ore 30-60%, gypsum 10-20%, refined mirabilite 15-35%, and lime 5-10%. The advantages of the invention include reduced cement clinker combustion temperature and increased secondary grinding effect.
Description
Technical field: the invention is used for burning till of cement clinker and grinding process.
Background technology: at present, China's building trade development rapidly, being in great demand of cement, and manufacture of cement is the rich and influential family of energy consumption, reduce the energy consumption of producing cement, improve cement quality, the environmental pollution that the minimizing manufacture of cement causes is a great scientific research task of national development, the research of carrying out the various admixtures of cement is arranged, existing up till now mineralizer at raw material, at the exciting agent of blended material, excite mixture activity but in cement clinker and raw material production, promptly reduce the cement clinker firing temperature again can be the time, and have the admixture of grinding-aid effect not have this product in the market at secondary grinding.So in cement production process, still consume the very big energy.
Summary of the invention: the purpose of the invention provides a kind of cement highly efficient catalyzer that can reduce energy consumption in cement production process; The purpose of the invention is achieved through the following technical solutions: the cement highly efficient catalyzer, it is characterized in that being made up of rare earth ore, sulphur iron ore, gypsum, Sodium sulfate anhydrous.min(99) and unslaked lime, each component is rare earth ore 5-10%, sulphur iron ore 30-60%, gypsum 10-20%, unslaked lime 5-10%, Sodium sulfate anhydrous.min(99) 15-35% in the gross weight ratio.
Each component effect of the invention: rare earth ore: play fluxing action; Sulphur iron ore: rise to increase and burn till heat and mineralization; Gypsum: play the chemical coordination effect, reduce fusing point, unslaked lime and Sodium sulfate anhydrous.min(99): play grinding aid and dispersion and chemi-excitation effect.
Cement highly efficient Application of Catalyst: in cement production process, after grinding ore, add the cement highly efficient catalyzer by 1% of cement slurry weight.
The advantage of the invention: because of containing rare earth ore, sulphur iron ore, gypsum, Sodium sulfate anhydrous.min(99), unslaked lime in the cement highly efficient catalyzer; Rare earth ore plays fluxing action, and sulphur iron ore plays to increase and burns till heat and mineralization, and gypsum plays the chemical coordination effect, reduces fusing point, has therefore reduced the cement firing temperature, and consumption of coal reduces; Again because unslaked lime and Sodium sulfate anhydrous.min(99) play grinding aid and dispersion and chemi-excitation effect, therefore in the consumption of secondary grinding time power saving, the simultaneous excitation mixture activity.
Embodiment: cement highly efficient catalyzer: be made up of rare earth ore, sulphur iron ore, gypsum, unslaked lime and Sodium sulfate anhydrous.min(99), each component is rare earth ore 5-10%, sulphur iron ore 30-60%, gypsum 10-20%, unslaked lime 5-10%, Sodium sulfate anhydrous.min(99) 15-30% in the gross weight ratio.
Embodiment: the cement highly efficient catalyzer of preparation 1000kg:
(1), above-mentioned each component is milled to ball mill pours reactor behind the fine powder (the 0.08mm square hole sieves) into and stir and promptly be mixed with the cement highly efficient catalyzer by gross weight weighing 5% rare earth ore 50kg, sulphur iron ore 300kg, the gypsum 200kg of weighing 20% of weighing 30%, the Sodium sulfate anhydrous.min(99) 350kg of weighing 35%, the unslaked lime 100kg of weighing 10%.
(2), above-mentioned each component is milled to ball mill pours reactor behind the fine powder (the 0.08mm square hole sieves) into and stir and promptly be mixed with the cement highly efficient catalyzer by gross weight weighing 10% rare earth ore 100kg, sulphur iron ore 600kg, the gypsum 100kg of weighing 10% of weighing 60%, the Sodium sulfate anhydrous.min(99) 150kg of weighing 15%, the unslaked lime 50kg of weighing 5%.
(3), above-mentioned each component is milled to ball mill pours reactor behind the fine powder (the 0.08mm square hole sieves) into and stir and promptly be mixed with the cement highly efficient catalyzer by gross weight weighing 7.5% rare earth ore 75kg, sulphur iron ore 400kg, the gypsum 150kg of weighing 15% of weighing 40%, the Sodium sulfate anhydrous.min(99) 300kg of weighing 30%, the unslaked lime 75kg of weighing 7.5%.
(4), above-mentioned each component is milled to ball mill pours reactor behind the fine powder (the 0.08mm square hole sieves) into and stir and promptly be mixed with the cement highly efficient catalyzer by gross weight weighing 6.5% rare earth ore 65kg, sulphur iron ore 400kg, the gypsum 150kg of weighing 15% of weighing 40%, the Sodium sulfate anhydrous.min(99) 300kg of weighing 30%, the unslaked lime 85kg of weighing 8.5%.
(5), above-mentioned each component is milled to ball mill pours reactor behind the fine powder (the 0.08mm square hole sieves) into and stir and promptly be mixed with the cement highly efficient catalyzer by gross weight weighing 8.5% rare earth ore 85kg, sulphur iron ore 500kg, the gypsum 120kg of weighing 12% of weighing 50%, the Sodium sulfate anhydrous.min(99) 230kg of weighing 23%, the unslaked lime 65kg of weighing 6.5%.
In cement production process, behind cement ore grinding, add the cement highly efficient catalyzer by 1% of cement slurry and carry out homogenizing, fire again, because rare earth has meltable effect, sulphur iron ore rises to increase and burns till heat and mineralization, gypsum plays the chemical coordination effect, reduce fusing point,, can economize coal 15-20kg/ ton cement so reduce 100-150 ℃ of cement firing temperature when firing, unslaked lime and Sodium sulfate anhydrous.min(99) play grinding aid and dispersion and chemi-excitation effect, so can save grinding electricity consumption 10%-20%/ton cement during secondary grinding, the simultaneous excitation mixture activity improves 28 days intensity 5-10Mpa of cement.
