It is also equipped with limestone, gypsum crushing, conveying and adding equipment. This production system is referred to as the "two grinding and one burning" system, that is, raw material mill, cement mill and rotary kiln burning. The entire production process is centrally controlled by an advanced distributed computer control system, which has the characteristics of high automation, stable process and strong reliability.The cement production process includes the stages of raw material mining and transportation, raw meal preparation, pulverized coal preparation, clinker burning and cement grinding. The main production process is that after limestone and auxiliary raw materials (glue, silica) are crushed, they are matched with treated industrial waste in appropriate proportions, crushed by a vertical raw material mill to prepare raw meal, and then enter the raw material homogenizing pile for homogenization treatment. It enters the rotary kiln through the 5-stage sealed external calciner (RSP), burns the clinker in a high temperature state, and enters the clinker storage: it is then crushed by a cement mill equipped with a compilation press, and finally forms various types of cement products. . The production process flow is shown in Figure 3.1. 公司水泥生产线由立式原料磨、5 级容外分解炉、转窑和配有辊压机的大型球磨机(水泥磨)等主要设备组成，同时设有石灰石、石膏粉碎及输送添加等设备。该生产系统简称为“两磨一烧”系统，即原料磨、水泥磨和回转窑焚烧。整个生产工艺采用先进的集散型计算机控制系统进行中央控制，其具有自动化高、工艺稳定、可靠性强的特点。水泥的牛产过程包括原料开采及运输、生料制备、煤粉制备、熟料烧和水泥粉磨等阶段。生产流程主要是石灰石及辅助原料(粘上、硅石)破碎后，与处理过的工业废弃物按适当比例搭配，经立式原料磨粉碎制备成生料，进入原料均化堆进行均化处理再经由5 级密外分解炉(RSP) 进入回转窑，在高温状态中烧成熟料，进入熟料储库:然后由配备辑压机的水泥磨进行粉碎，最终形成各种不同种类的水泥产品。生产工艺流程详见图 3.1。 The Portland-composite cement produced using this industrial process is intended for construction purposes, including the production of concrete, mortar, and other building materials. The cement is created through a modern dry process using a rotary kiln and has a daily capacity of 4000 tons. It incorporates complex silicate compounds and a mix of industrial by-products and solid wastes to minimize environmental impacts, aligning with sustainable development principles in the construction industry. 使用此工业过程生产的复合硅酸盐水泥旨在用于建筑目的，包括混凝土、砂浆和其他建筑材料的生产。该水泥通过使用回转窑的现代干法过程产生，每日产能为4000吨。它结合了复杂的硅酸盐化合物和一系列工业副产品及固体废物，以最小化环境影响，符合建筑行业的可持续发展原则。 BcVbbuMN8oTaxyxbBjKc8isHnBg.png The system boundaries are raw meal preparation, pulverized coal preparation, clinker calcination, and cement grinding.

When utilizing this dataset, ensure that all stages from raw meal preparation to cement grinding are included in the system boundaries. The database user should recognize that the functional unit is 1 ton of cement product, which is essential for comparison with other datasets. Methodological attention should be paid to the inclusion of industrial waste treatment and the allocation procedures for co-products and environmental burdens. Users should ensure their LCA studies are consistent with the technological applicability of the equipment and processes described, especially the 'two mills and one kiln' system with high automation and reliability.
