Method for producing silicate clinker by replacing silicon-aluminum raw material ingredients with modified coal gangue
The invention discloses a method for producing silicate clinker by replacing silicon-aluminum raw material ingredients with modified coal gangue. The method comprises the following steps of: (1) modifying coal gangue; (2) preparing raw material powder from the modified coal gangue instead of a silicon-aluminum raw material, and carrying out pre-decomposition; and (3) adjusting the use amount of tailings, oxidizing and calcining. According to the invention, the problem that the working condition stability of the kiln system is influenced by serious crusting and sticking of the kiln system due to the characteristics of the raw coal gangue can be solved, so that large-scale consumption of the coal gangue by cement enterprises is facilitated, and the problem of environmental pollution caused by coal gangue accumulation is solved.
改性煤矸石替代硅铝质原料配料生产硅酸盐熟料的方法，包括如下步骤：（1）改性处理煤矸石；（2）改性煤矸石替代硅铝质原料配料制生料粉和预分解；（3）调节尾煤用量、氧化煅烧。本发明可解决因生煤矸石的特性导致在窑系统产生严重的结皮粘堵影响窑系统工况稳定性等问题，以便于水泥企业大规模消纳煤矸石，化解煤矸石堆积带来的环境污染问题。
