The company's production process uses RSP five-stage kiln external decomposition technology, and mainly adopts advanced production equipment from Germany, France, Japan, and some domestic companies. The cement production line consists of a vertical raw mill, a 5-stage RSP (kiln external pre-decomposition tower), a rotary kiln, and a large ball mill equipped with a roller press, as well as gypsum crushing, limestone grinding, and conveying and adding equipment. When using this LCA dataset, the user should consider the technological applicability of the RSP five-stage kiln external decomposition technology and the specific context of production in Dalian, China. Due to the difficulties in data collection, the users should exercise caution regarding the emission factors and may need to adjust them based on locale-specific environmental regulations and emission data. Users should also take into account that the data may need to be converted to reflect energy and raw material relationships, and that the LCA method was not used for modeling in this dataset.
