Description

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. Users of this LCA dataset should be aware that it includes production process data from DOCC, which applies advanced RSP kiln external decomposition technology. Data was not modeled using LCA methodology but was obtained through on-site surveys and indirect calculation of energy and raw material conversion due to the lack of direct industrial pollutant emissions data. Users should also note potential methodological differences and understand that the dataset may not include end-of-life recycling or use-phase behavior modeling. It's recommended to cross-reference this data with the latest available standards and industry practices, especially regarding emission factors and environmental impacts.

Technology

The company now has a 4000t/d modern dry process production line (RSP kiln external decomposition equipment) as shown in Figure 6.2, its own independently mined open-pit limestone mine (annual limestone production capacity of 2 million tons) and a dedicated railway line in the factory. The special line for bulk cement outputs the terminal, with an annual cement production of 1.9 million tons.The company's production process adopts RSP five-stage kiln external decomposition technology, mainly using advanced production equipment from Germany, France, Japan and some domestic countries. The cement production line consists of main equipment such as a vertical raw material mill (as shown in Figure 6.1), a 5-stage RSP (pre-calcining tower outside the kiln), a rotary kiln and a large ball mill equipped with a roller press. It is also equipped with gypsum crushing and limestone crushing and conveying and adding equipment.
