The invention belongs to the technical field of cement processing, and particularly relates to a cement manufacturing process which can be used for efficiently preparing half-dry cement with good smoothness. The process comprises the following steps: S1, adding 0.02%-0.23% of a correction raw material into a limestone raw material and a clay raw material; S2, crushing and homogenizing the materials in the S1, and carrying out mixing according to a certain proportion to prepare a raw material; S3, feeding the prepared qualified raw material into a cement kiln to be calcined until part of the raw material is molten, and preparing clinker; S4, cooling the clinker; S5, adding gypsum and a mixed material into the cooled clinker, and jointly grinding the clinker and the mixed material into powder; S6, processing the cement prepared in the step S5 into half-dry cement through a cement prefabricating device; S7, in the processing process, sucking out the bubbles in the half-dry cement.
本发明属于水泥加工技术领域，尤其是一种水泥制造工艺，该技术能够高效地制备出平整性好的半干水泥；该工艺包括以下步骤：S1：在石灰石原料和黏土质原料中加入0.02％‑0.23％的校正原料；S2：将S1中的材料进行破碎、均化后，按照一定比例进行混合，制备生料；S3：将制备合格的生料送入至水泥窑内煅烧至部分熔融，制备熟料；S4：对熟料进行冷却；S5：在冷却完成的熟料中加入石膏和混合材后，共同研磨至粉末状；S6：通过水泥预制装置将S5中的制备的水泥加工成半干水泥；S7：加工过程中，将半干水泥中的气泡吸出。
