Production method for calcining cement clinker by using lignite
The invention relates to the field of cement clinker production methods, discloses a production method for calcining cement clinker by using lignite, and provides the following scheme aiming at the problem of high cost of a cement clinker calcining method in the prior art: the production method comprises the following steps: S1, selecting 80-100 parts by weight of lignite and 40-60 parts by weight of anthracite, mixing and crushing to obtain a mixture A; mixed raw coal is obtained; s2, the mixed raw coal in the step S1 is ground into powder and dried, then the dried coal powder is screened, and therefore qualified coal powder is obtained; s3, feeding the pulverized coal obtained in the step S2 into a pulverized coal bunker for storage for later use; and S4, feeding the pulverized coal in the pulverized coal bunker into a combustor for combustion by using a Roots blower. According to the invention, the production cost can be effectively reduced, the operation is very convenient, and the improvement of the production efficiency is facilitated.
本发明涉及水泥熟料生产方法领域，公开了一种利用褐煤煅烧水泥熟料的生产方法，针对现有技术中的煅烧水泥熟料方法成本高的问题，现提出如下方案，其包括以下步骤：S1、选取80‑100重量份的褐煤和40‑60重量份的无烟煤进行混合破碎，得到混合原煤；S2、将S1步骤中的混合原煤磨粉，并且烘干，然后再对烘干后的煤粉进行筛分，从而得到合格煤粉；S3、将S2步骤中得到的煤粉送入煤粉仓中进行储存备用；S4、利用罗茨风机将煤粉仓中的煤粉送入燃烧器燃烧。本发明不仅可以有效降低生产成本，而且操作起来非常的方便，有助于生产效率的提高。
