One of the raw materials, limestone, enters the crushed stone storage after crushing. The raw clay and iron powder enter the dry clay storage and iron powder storage respectively after drying. Fuel anthracite is crushed by the coal crusher (sometimes also dried) to enter the raw material storage, at the bottom of the storage by the downstream, metering equipment in proportion to the exact match and sent to the raw material mill grinding. After the qualified grinding, the raw material enters the raw material storage for homogenization and storage. The homogenized raw meal is combined with a suitable amount of water after metering, forming balls in the raw meal ball-making system, and then sent to the upper part of the vertical kiln, sprinkled into the kiln through the material distributor, and clinkered. The clinker from the kiln is stored in the clinic storage; the mixed material is also stored in the storage after baking in the drier; the gypsum is crushed and entered the gypsum storage. After being metered, the clinker, mixed materials, and a suitable amount of gypsum are sent to the cement plant for proportionate grinding. The ground cement is sent to the cement warehouse for inspection and final packaging or bulk delivery. 典型机械化立窑水泥厂。立窑生产工艺流程相对简单，原料之一的石灰石经破碎机破碎后进入碎石库，原料粘土、铁粉经烘干后分别进入干燥的粘土库、铁粉库。燃料无烟煤经碎煤机破碎后（有时也要烘干）进入原料库，在库底经下料、计量设备按比例准确配合后喂入生料磨粉磨。经粉磨合格后的生料入生料库进行均化、存储。均化后的生料经计量与适量水配合，在生料成球系统中进行成球，然后送入立窑上部经布料器撒入窑内煅烧成熟料。出窑熟料进入熟料库中存储；混合材料经烘干机烘千后也入库存储；石膏经破碎后进入石膏库。熟料、混合材料和适量石膏经计量后按比例配合送入水泥磨中粉磨，粉磨合格后的水泥送入水泥库中，经检验，最后进行包装或散装出厂。 9 2005 The vertical kiln production process is relatively simple. Limestone, one of the raw materials, is crushed by the crusher 1 and then enters the gravel storage. The raw materials clay and iron powder are dried and then enter the dry clay storage and iron powder storage respectively. The fuel, anthracite, is crushed by a coal crusher (sometimes also dried) and then enters the raw material warehouse. At the bottom of the warehouse, the raw material is fed into the raw material mill 5 and ground after accurate mixing by the measuring equipment according to the proportion. The raw materials that have been grinded and qualified are put into the raw material warehouse 6 for homogenization and storage. The homogenized raw meal is measured and mixed with an appropriate amount of water, and is pelletized in the raw meal pelletizing system 7, and then sent to the upper part of the vertical kiln, spread into the kiln through a distributor, and forged into clinker. The clinker coming out of the kiln enters the clinker warehouse 10 for storage; the mixed materials are also stored in the warehouse after being dried by the dryer; the gypsum enters the gypsum warehouse after being crushed. The clinker, mixed materials and appropriate amount of gypsum are measured and mixed according to the proportion and sent to the cement mill for grinding. The cement after grinding is sent to the cement warehouse 14, inspected, and finally packaged or shipped in bulk. 立 窑生 产 工艺 流程 相对 简单 原 料 之一的石 灰 石 经破 碎机 1 破 碎 后 进入 碎 石 库，原 料 粘土 、 铁 粉经 烘 干 后分别进入干 燥 的 粘 土 库 、 铁粉库 。 燃 料 无 烟 煤 经 碎煤机破 碎 后 ( 有 时 也 要烘干 ) 进 入原料 库，在 库 底 经 下 料 、 计 量 设 备按 比 例 准 确 配合后 喂入生 料 磨 5 粉 磨 。 经 粉 磨合 格 后 的生 料入 生 料 库 6 进行 均化 、 存储 。 均 化 后 的 生料经计量与适量水配 合，在 生 料成 球 系 统 7 中进行成球，然后送入立窑 上 部 经 布 料器 撒 入 窑内 锻 烧 成 熟料 。 出 窑 熟料进 入 熟 料 库 10中 存 储 ; 混合 材料 经 烘干 机烘千 后也 入 库 存储 ; 石 膏 经 破 碎 后 进 入 石 膏库 。 熟料 、 混合 材 料 和适 量 石 膏 经计量后 按 比 例 配 合 送 入 水 泥 磨中粉 磨，粉 磨合 格 后 的 水 泥 送 入水 泥 库 14 中，经检验，最 后 进行 包 装 或 散装 出 厂 。 This dataset describes the production process of ordinary Portland cement with a compressive strength of 42.5MPa using a mechanical shaft kiln.
