construction site, many buildings rise from the ground, and equipment installation is carried out in an orderly manner. Recently, at the construction site of Witton Cement Group's digital and intelligent green factory technology transformation project, the construction wave is in full swing, and the construction personnel go all out to rush the construction period, catch up with the progress, and run out of the "acceleration" of the project construction. Zhang Yanjun, Director of Technical Development Department
of Witton Cement Group Co., Ltd.: The main civil works of the raw material grinding and firing system in the production line of our project have been completed, and the main equipment such as the raw material roller press, rotary kiln, preheater and cooler have been installed in place. At present, the electrical equipment has entered the installation stage, and it is planned to be commissioned in April and put into operation in March 2024.
In order to realize the major transformation and upgrading of cement production technology, Witton Cement Group has carried out the technical transformation of the existing production line into a digital and intelligent green factory, through the "equivalent replacement" of production capacity. A second generation new dry process cement clinker production line with a daily output of 4500 tons and a special cement clinker production line with a daily output of 1500 tons will be built, and 50000 tons of hazardous waste and 400 tons of domestic waste will be disposed of annually. It also integrates and applies the most advanced design concepts, technologies and equipment in the cement industry to transform the whole plant into a digital and intelligent green plant from the aspects of intelligent control, intelligent logistics, intelligent management, intelligent service and digital mine.
This project adopts the second-generation new dry-process cement technology and equipment, and selects the high-efficiency and low-nitrogen double-series six-stage pre-decomposition system and the high-efficiency energy-saving material bed grinding technology, so that the unit pollutant emission is reduced by 50%, the energy consumption is reduced by 15%, and the standard coal 17000 can be saved by more than tons every year, which has good economic and social benefits. Zhang Yanjun, Director of Technical Development Department
of Witton Cement Group Co., Ltd.: After the project is completed and put into operation, it will become the largest special cement production base in North China. The energy consumption of cement products meets the requirements of the national first-class energy consumption index, and the emission meets the national ultra-low emission requirements.
According to public information, Witton Cement Group Co., Ltd. is a large-scale modern cement production enterprise designed to produce 6 million tons of new dry cement annually, located in Shimenyukou, Zezhang Town, Xinjiang County, Shanxi Province, with registered capital of 33180 million yuan and total assets of 1.29 billion yuan.
The company takes cement manufacturing as the main industry, extends the industrial chain, develops diversified related industries, including mining, construction aggregate, waste heat power generation, hazardous waste disposal, domestic waste treatment, commercial concrete, dry-mixed mortar and other diversified industries, and gradually transforms from a single cement industry to a green environmental protection industry. It is a major special cement production enterprise in North China, one of the top 100 cement clinker production enterprises in China, and one of the top 500 building materials enterprises in China.
