Cement clinker and preparation process thereof
The invention relates to a cement clinker and a preparation process thereof, and belongs to the technical field of cement preparation. The cement clinker is prepared from the following raw materials in percentage by weight: 65%-68% of limestone, 4.5%-6% of sandstone powder, 7.5%-8.5% of fly ash, 4%-5.5% of converter slag, 8%-10% of carbide slag and 8.00%-12% of magnesium slag. The preparation process comprises the following steps: mixing the raw materials according to the weight ratio; drying and grinding the mixed raw materials to obtain a raw material; the raw material is conveyed to a five-stage preheater through a kiln elevator to be preheated, the preheated raw material enters a decomposing furnace through a discharging pipe to be decomposed, and hot raw material powder is obtained; and putting the hot raw material powder into a rotary kiln for calcining to form the cement clinker. The cement clinker is produced by using the waste magnesium slag, so that the pollution of the magnesium slag to the environment can be reduced, and the heat consumption from raw materials to the clinker can be reduced to a certain extent.
本发明涉及一种水泥熟料及其制备工艺，属于水泥制备技术领域。水泥熟料由以下重量比的原料配制而成：石灰石65％‑68％，砂岩末4.5％‑6％，粉煤灰7.5％‑8.5％，转炉渣4％‑5.5％，电石渣8％‑10％，镁渣8.00％‑12％。制备工艺包括：将各原料按照以上重量比例进行混合；将混合后的原料烘干、粉磨，得到生料；将生料通过入窑提升机输送至五级预热器进行预热，预热后的生料通过下料管进入到分解炉进行分解，得到热生料粉；将热生料粉放入回转窑进行煅烧，形成水泥熟料。通过利用废弃的镁渣进行水泥熟料的生产，不仅可以减少镁渣对环境的污染，而且可在一定程度上减少生料到熟料的热耗。
