Method for producing silicate clinker by using coal gangue instead of tailings and silicon-aluminum raw materials
The invention relates to a method for producing silicate clinker by using coal gangue instead of tailings and silicon-aluminum raw materials. The method comprises the following steps: (1) preparationof double-component powder; (2) preheating, mixing and decomposing; and (3) oxidizing calcination. According to the invention, the problems of influence on clinker production quality, energy consumption and the like due to crusting and sticking caused by the characteristics of raw coal gangue can be solved; and a large amount of raw coal gangue is consumed, and meanwhile, a part of tailings and silicon-aluminum raw materials used in dry cement produced are replaced, so the coal consumption of cement production and the consumption of clay (shale) type silicon-aluminum raw materials are reduced,and the problem of environmental pollution caused by coal gangue accumulation is solved.
一种利用煤矸石替代尾煤和硅铝质原料生产硅酸盐熟料的方法，包括以下步骤：（1）双组分制粉；（2）预热、混合、分解；（3）氧化性煅烧。本发明可解决因生煤矸石的特性产生的结皮粘堵影响熟料产质量、能耗等问题，大量消纳生煤矸石同时替代干法水泥生产的部分尾煤和硅铝质原料，降低水泥生产的燃煤消耗和粘土（页岩）类硅铝质原料的消耗，解决煤矸石堆积带来的环境污染问题。
