China Drying Network News China's dry calcium carbide slag dry cement process developed by Xinjiang Tianye has recently obtained national invention patents. The technology uses 100% calcium carbide slag, lime slag and calcium carbide dust collection ash as a limestone raw material to produce cement clinker, using a dry-grinding dry-burning new dry clinker production process and a combined extrusion cement grinding process. Compared with the wet-milled dry clinker process, the new process has a large scale of production, low energy consumption, and significant energy savings. Xinjiang Tianye calcium carbide slag new dry cement production line is the first large-scale industrialized operation device in China, which solves the environmental pollution caused by acetylene chemical waste residue. In 2012, Xinjiang Tianye dry process acetylene-supported carbide slag dry cement project was successfully selected as the first batch of major demonstration projects of recycling economy by the Ministry of Industry and Information Technology of the People's Republic of China, which played an exemplary role in comprehensively improving the technical level of clean production of PVC by calcium carbide process and promoting the development of circular economy in the PVC industry. . At present, Tianye has built five production lines using this technology, and has an annual output of 3.7 million tons of cement.
