The invention belongs to the technical field of cement processing, and particularly relates to an anti-crack cement production process. The process comprises the following steps: step 1, checking the dry and wet conditions of limestone in a stockpile, and conveying the limestone to a position above an opening in the upper side of a double-plate type crushing and extruding machine by utilizing a feeding belt in a pre-homogenization stockpile; secondly, the initially-conveyed large limestone materials are intercepted through a frame plate with the adjustable inclination angle, and the large limestone materials are moved out of an opening in the upper side of the double-plate type crushing and extruding machine; 3, the limestone materials are extruded through pressing plates on the two sides, the block size of the limestone materials on the feeding belt is detected in real time, and the extrusion interval of the pressing plates on the two sides is changed; 4, conveying the crushed limestone, drying at 30-50 DEG C for 10-15 minutes, and sieving with a 500-mesh sieve; and 5, adding the clay raw material and a small amount of the iron correction raw material into the calcareous raw material, grinding and firing to prepare clinker, and adding the anti-cracking agent in the process of firing and grinding again.
本发明属于水泥加工技术领域，具体而言，是一种抗裂水泥生产工艺；该工艺包括以下步骤：步骤一：检查堆料中的石灰石的干湿情况，在预均化堆场中利用进料皮带，将石灰石向双板式破碎挤压机上侧开口上方处进行输送；步骤二：利用倾斜角度可调的框板将初始输送的大块石灰石料进行拦截，使大块石灰石料从双板式破碎挤压机上侧开口处移出；步骤三：利用双侧压板对石灰石料进行挤压，并实时检测进料皮带上的石灰石料的块状大小，改变双侧压板的挤压区间；步骤四：对粉碎后的石灰石碎料进行输送，30‑50℃干燥10‑15min后，过500目筛；步骤五：在石灰质原料中，加入黏土质原料和少量铁质校正原料后研磨烧制，制成熟料后，再次烧制粉磨过程中，添加抗裂剂。
