Competitiveness "magic weapon"! Dongfang hopes that the energy-saving effect of Chongqing Cement "5 to 6" project is remarkable!

this year, poor demand, falling prices and high inventory have worsened the downturn in the cement industry.

When survival becomes extremely difficult, how can cement enterprises base themselves on the current market environment and improve their competitiveness? "Energy saving and carbon reduction, cost reduction and efficiency enhancement" has become a magic weapon for many cement enterprises to save themselves in the face of difficulties.

Just a few days ago, China Cement Network and its delegation visited Oriental Hope Chongqing Cement. At the stage of "chill" in the cement industry, Dongfang hopes that Chongqing Cement has written a story of enterprise progress with its own strength. As a traditional manufacturing enterprise

, Dongfang Hope Chongqing

Cement is very "special". Since its establishment, the company has been adhering to the concept of green sustainable development of Chairman Liu Yongxing of the Group. Through continuous energy-saving and environmental protection technology transformation, it has changed people's traditional understanding of cement plants and set an example for the green and high-quality development of the cement industry.

, especially the successful application of the preheater "5 to 6 project", has attracted the attention of the whole industry.

In the cement industry, most of the 5000t/d production lines are 5-stage preheaters, except for individual cement enterprises built in recent years. In recent years, with the in-depth research of preheater technology, the industry has gradually realized that 6-stage preheater has great advantages in reducing production energy consumption, but the transformation of preheater is difficult and risky. For many years, no cement enterprise has dared to try to change 5-stage preheater to 6-stage preheater. Dongfang hopes that Chongqing Cement will become the first enterprise in the industry to "eat crabs".

According to the technical director of Dongfang Hope Chongqing Cement Production, the "5 to 6" project of Dongfang Hope Chongqing Cement Line 3 was completed in September 2022, and the "5 to 6" project of Line 2 was also completed in April this year. After the completion of the transformation, Dongfang hopes that the energy consumption index per ton of cement clinker in Chongqing will decrease significantly, and the overall energy consumption level will be in the forefront of the industry. The "5 to 6" preheater

is just a microcosm of the green and sustainable development of Chongqing Cement. In recent years, Dongfang hopes that Chongqing Cement will continue to intensify its technological transformation efforts, and the cost of technological transformation in 2022 alone will be close to 300 million yuan. Now, in Dongfang Hope Cement Plant, the application of new technologies can be seen in all links that can effectively reduce production energy consumption, ranging from fans, pumps, air compressors to grate coolers, vertical mills, preheaters and other main equipment, which can be called the "Exhibition Hall of Advanced Technologies in Modern Cement Industry".

in addition, from plant environmental governance to pollutant emission reduction, from carbon emission reduction to mine governance. From staff environmental protection knowledge training to village-enterprise co-construction to create "ecological civilization village", Dongfang hopes that Chongqing Cement will implement the concept of environmental protection in all aspects of production and operation, and a modern green factory has stood proudly on the bank of the Yangtze River. On July 6-7,

2023, China Cement Network will hold the " 2023 China Cement Energy Conservation and New Energy Development Conference " in Chongqing, starting from energy-saving transformation, photovoltaic, energy storage and other technology applications, green power, alternative fuels to replace tradi tional energy transformation, and so on. Explore new ways of energy saving and consumption reduction in cement industry.

After the meeting, we will visit Dongfang Hope Chongqing Cement Preheater "Level 5 to Level 6" Energy-saving Demonstration Line and Steam-driven Fan Energy-saving Project.
