Environment-friendly high-performance cement and preparation method thereof
The invention belongs to the technical field of cement processing, and particularly relates to environment-friendly high-performance cement and a preparation method thereof. The method comprises the following steps: S1, preparing limestone, clay, slag powder, magnesium silicate and other raw materials; s2, the raw materials are fully scattered through a configuration device, so that the granularity of the raw materials is more uniform; s3, mixing clay, slag powder, magnesium silicate and other raw materials to obtain a prefabricated material, conveying the prefabricated material to a roller press for extrusion and grinding, and drying the prefabricated material in the grinding process; s4, carrying out secondary crushing on the dried prefabricated material, and adding limestone in the process; s5, the cement materials are scattered and sorted through a scattering machine, coarse particles with the particle size larger than 2.8 mm are conveyed to the roller press again to be ground again, and cement raw materials with the particle size smaller than 0.5-1.8 mm are conveyed into a grinding machine to be ground; the environment-friendly high-performance cement is prepared from the following components in parts by mass: 10 to 20 parts of limestone, 20 to 40 parts of clay, 13 to 18 parts of slag powder and 15 to 20 parts of magnesium silicate. And the prepared cement has a good environment-friendly effect.
本发明属于水泥加工技术领域，具体而言，是一种环保型高性能水泥及其制备方法；该方法包括以下步骤：S1：制备石灰石、黏土、矿渣粉和镁硅酸盐等原料；S2：通过配置装置将原料充分打散，使其颗粒度更为均匀；S3：将黏土、矿渣粉和镁硅酸盐等原料混合后，得到预制材料，输送至辊压机进行挤压碾碎，并在粉磨过程中对预制材料进行烘干；S4：对烘干后的预制材料进行二次碾碎，在此过程中加入石灰石；S5：通过打散机对水泥材料进行打散分选，将2.8mm以上粗颗粒重新输送至辊压机进行重新粉磨，小于0.5‑1.8mm的水泥原料，送入粉磨机粉磨；该环保型高性能水泥的组成为：按照质量份数取石灰石10‑20份、黏土20‑40份、矿渣粉13‑18份和镁硅酸盐15‑20份；制成的水泥环保效果较好。
