System and method for calcining cement clinker by independently feeding coal gangue
The invention belongs to the technical field of application of coal gangue in cement production, and particularly relates to a system and a method for calcining cement clinker by independently feeding coal gangue, and the method for calcining cement clinker by independently feeding coal gangue comprises the following steps: feeding cement raw materials except coal gangue into a preheater; the fineness of the coal gangue is controlled to be less than or equal to 10% by 80-micron screen residue, and the coal gangue is put into a blanking pipe of the penultimate-stage cyclone preheater; the invention provides a system and a method for calcining cement clinker by independently feeding coal gangue, which can improve the use amount of coal gangue and can consume and utilize more coal gangue in the cement production process.
本发明属于煤矸石在水泥生产中应用技术领域，尤其涉及一种煤矸石单独喂料煅烧水泥熟料的系统和方法，所述煤矸石单独喂料煅烧水泥熟料的方法包括以下步骤：除煤矸石以外的水泥生料喂入预热器；将煤矸石细度控制80微米筛余小于等于10％，投入倒数第二级旋风预热器下料管。本发明提供一种提高煤矸石用量，能在水泥生产过程中消纳和利用更多煤矸石的煤矸石单独喂料煅烧水泥熟料的系统和方法。
