This phase consists entirely of physical processes; no chemical processes are involved, as described and depicted in Fig. 5. The clinker from the cement kiln, mixed together with gypsum and other additives, is milled into fine particles of a particular size in the cement milling sub-system, which are a final product of cement. This phase consists entirely of physical processes; no chemical processes are involved, as described and depicted in Fig. 5. The technical application of this data set is targeted towards the cement milling industry. The described cement milling process involves grinding clinker produced from a shaft kiln, with the inclusion of gypsum and alternative constituents ranging from 21-35%, into a fine powder to achieve the final cement product. This milled cement is generally used for construction purposes, including concrete production, infrastructure development, and building construction. The process is characterized by physical grinding without any chemical reactions and refers to production lines associated with vertical kilns, which typically have high energy demands and low production efficiency. 该数据集的技术应用针对的是水泥磨制行业。描述的水泥磨制过程涉及将立窑生产的熟料与石膏以及21-35%的替代成分磨成细粉，以获得最终的水泥产品。这种磨制的水泥通常用于建筑目的，包括混凝土生产、基础设施开发和建筑施工。该过程的特点是物理磨粉而无化学反应，并且指的是与立式窑生产线相关的过程，这些生产线通常具有高能耗和低生产效率。 MvDgbrj8JobZ7IxUGAvc7mwZnCd.png The system boundary is the grinding stage where cement is produced. 系统边界为产生水泥的研磨阶段。 Unit process, single operation None 无 None 无 None 无 None 无 None 无 Dan Hu, Zhen Guo, Zhen Wang, & Qiang Xiao.

Ecological Informatics 26, 70–77. After investigation, the annual production capacity of cement companies using vertical kiln production systems is 100,000 tons of clinker. The overall characteristics of shaft kiln production lines are high energy consumption, limited production capacity, low labor productivity, and large dust emissions. The dynamic metabolism analysis of the shaft kiln production line is carried out in units of 1 hour under normal production levels. 经调查，采用立窑生产系统的水泥企业的年产能为100,000吨熟料。立窑生产线的总体特点是能耗高，生产能力有限，劳动生产率低，粉尘排放量大。立窑生产线的动态代谢分析是在正常生产水平下以1小时为单位进行的。 When using this dataset for Life Cycle Assessment (LCA) of cement produced with alternative constituents in a shaft kiln, note the specific conditions such as the percentage of alternative materials (21-35%) and the energy consumption characteristics of the production process. Consider the technological applicability to the targeted region or industry. Ensure inclusion of all relevant inputs and outputs in the system boundary for accurate representation, and account for high dust emissions in the environmental impact assessment. Avoid extrapolating the data to processes different from those described, such as those using rotary kilns, which may have different technological and environmental profiles. 在使用这份数据集进行含替代成分立窑生产的水泥的生命周期评估（LCA）时，请注意特定条件，例如替代材料的百分比（21-35%）和生产过程的能耗特征。考虑技术的适用性到目标区域或行业。确保在系统边界内包含所有相关输入和输出，以准确表示，并在环境影响评估中计算高粉尘排放。避免将数据外推到与描述的过程不同的过程，如使用回转窑的过程，这些可能有不同的技术和环境概况。 Inventory: The internal review was done by several iteration steps concerning raw data validation, raw data documentation, representativity, completeness and consistency of modelling with regard to ISO 14040 and 14044. 清单： 内部审查通过几个迭代步骤完成，涉及原始数据验证、原始数据记录、代表性、完整性、与 ISO 14040 和 14044 有关的建模的一致性。 Tiangong LCI Data Working Group 天工LCI数据工作小组 #REF!, ysqsophia@gmail.com ysqsophia@gmail.com ysqsophia@gmail.com 2024-03-19T21:18:09+08:00 2024-04-20T14:42:06.637092+08:00 00.01.005 https://lcadata.tiangong.world/showProcess.xhtml?uuid=44d5e3c7-655d-4bab-b7e1-7574a497d724&version=01.00.000&stock=TianGong Tiangong LCI Data Working Group 天工LCI数据工作小组 false Free of charge for all users and uses clinker Input 867.679 867.679 Cement clinker 水泥熟料 mixed materials, mineral Input 91.829 91.829 Mixed materials 混合材料 gypsum stone (CaSO4-dihydrate) Input 46.276 46.276 Gypsum 石膏 freshwater Input 15.184 15.184 Water (water content): water contained in the input materials. 水（水含量）：输入材料中的水。 particles (> PM10) Output 5.785 5.785 Dust.
