Research And Studies Of The Production Line Of Pre-decomposed Low-alkali Cement For Pleateau

Exploring the effect of the pre-decomposed kiln combustion when the gas change of high elevation eara. It's very important for the developing of the new dry cement technology of production. But conquering the weakness that together of the recycle of pre-decomposed kiln's lime and sulfer and stabilizing producing super low lime material are also hot subject of modern cement science. According to the extended engineering of Yunnan sY cement factory this article makes a discuss about the developing of high elevation pre-decomposed low lime cement line of producing on side standing local resource condition, makes a great discuss for lime cement production technology. At the same time decides the plan of production with high silicon and low lime rock instead of low lime material that making with soil. According to material discuss, the experimention of material easy combustion and so on is good for the rational range with the best making of two high and one medium. At the sametime, we must strictly control the material and coal pellet' to be little, improre the temperature of flame in the kiln and the ration entering to the kiln as possible as we can to make up the weakness that high silicon soil making the good combustion character of material change bad and stabilize to produce super quality and low lime material and cement.At the same time this article also discuss the effect of the pre-decomposed kiln combustion when the gas change of high elevation eara (over 2000m), especially high elevation condition makes effectional way and degree for the process of combustion trasmiting heat and things of decomposed stone. Pre-heat vessel, recycle kiln and so on heart equipments makes advanced development in aims and makes whole advanced designing for 600t/d producing line of high elevation pre-decomposed kiln.From this producing line begins on, the system works well, day production is average to 617t/d, the average lime of material is only 0.19%. getting to the head level of hometown the material name gets to 60 Mpa every month. Making up Yunnan province weakness of low lime cement producing, the money is controlled in 5850000 Yuan. Camparing with the same dimension pre-heat vessel producing line less 10%. Providing a financial and technology aim for advice of pre-decomposed kiln producing line and low lime cement producing in hometown high elevation eara.
