Method for producing general cement clinker by partially replacing iron correction raw material with fly ash
The invention discloses a method for producing general cement clinker by partially replacing an iron correction raw material with fly ash. The method comprises the following steps: firstly, blending and mixing 99.0-99.6% of Portland cement raw material and 0.4%-1.0% of fly ash, and placing the mixture into a raw material homogenizing silo; drying and pre-decomposing the raw material through a preheater with a five-stage cyclone, calcining the material at high temperature after the decomposition rate reaches 95% or above, and cooling a product to form the general portland cement clinker. The improvement of the invention lies in that the fly ash is used for partially replacing an iron raw material to produce the cement clinker, so that the production cost of the cement clinker can be reduced, the usage amount of the fly ash can be increased, the fly ash is comprehensively utilized, and the environmental protection is facilitated.
本发明公开了一种采用粉煤灰部分替代铁质校正原料生产通用水泥熟料的方法，首先将硅酸盐水泥生料99.0％～99.6％；粉煤灰0.4％～1.0％进行调配、混合后入生料均化库；然后经带五级旋风筒的预热器进行烘干预分解，分解率达到95％以上后进行高温煅烧，然后冷却形成通用硅酸盐水泥熟料。本发明的改进之处在于用粉煤灰部分代替铁质原料生产水泥熟料，不仅能够降低水泥熟料的生产成本，而且能够提高粉煤灰的使用量，综合利用粉煤灰，有利于环境的保护。
