Brief Introduction of Ningguo Cement Plant in Anhui Province

Ningguo Cement Plant's new dry cement clinker production line with a daily output of 4,000 tons is a key construction project in China during the Sixth Five-Year Plan. The main equipment was imported from Mitsubishi Heavy Industries of Japan, and construction started in September 1982, and was officially put into production in July 1987. At the end of 1984, the State Planning Commission and the State Economic Commission approved Shanghai Shengli Cement Plant to be handed over to Ningguo Cement Plant for operation and management (three Huaxin wet rotary kilns with clinker production capacity of 200,000 tons/year and cement production capacity of 250,000 tons/year have been shut down); At the beginning of 2002, the new dry-process clinker production line with a daily output of 5,000 tons was started, and the construction period was 10 month, which achieved the goals of starting, putting into production and reaching production in the same year, and set a record of the shortest construction period, the least investment and the fastest production of similar kilns in the world.

The 6480 kW waste heat power generation system of the 4000-ton clinker production line in Ningguo Cement Plant belongs to the Sino-Japanese cooperative energy comprehensive utilization demonstration project, and it is the first set of pure low-temperature waste heat generator set in cement kiln in China. It was completed on199610 18 and put into operation on16 March 1998. The 9 100 kW waste heat power generation project with a daily output of 5,000 tons of clinker started on 28 October 2005. It is a waste heat power generation system independently designed, completed and built by Conch. It was completed and put into operation on July 29, 2006, and the construction was only nine months. Two sets of waste heat power generation systems can save more than 50,000 tons of raw coal and reduce carbon dioxide emissions by 6.5438+0.2 million tons every year.

Ningguo Cement Factory has always adhered to the management tenet of "quality first, sincere service" and obtained the product quality certification of "Conch brand" 52.5R grade II portland cement, 42.5R grade ordinary portland cement and "Conch brand" 32.5R grade composite portland cement. And ISO900 1:2000: 2000 quality system certification, iso14001:2004+0: 2004 environmental management system certification, OHSAS 1800 1 occupational health and safety management system certification.

Conch cement produced by Ningguo Cement Plant covers general civil and special-purpose fields, and has won wide praise from customers, especially key engineering customers, for its strong supply guarantee ability. Widely used in Hongqiao Airport, Oriental Pearl, Jinmao Building, Lianyungang Nuclear Power Station, Shanghai Maglev Train, Beijing Atomic Energy Fast Reactor, National Earthquake Monitoring Network and other world-renowned landmark and high-tech projects, it has established a cross-century image monument. Ningguo Cement Factory adheres to the business philosophy of "creating future living space for mankind", pursues common progress and development with society, and takes the road of ecological protection and coordinated development. Always attach importance to environmental treatment and clean production, pay attention to the comprehensive utilization of mine resources, expand the field of "three wastes" utilization and treatment, use the waste heat of kiln exhaust gas to generate electricity, develop new technologies for digesting industrial waste and domestic garbage into kiln for calcination, and configure environmental protection equipment according to national standards, so that dust emission and recovery, waste water and waste gas utilization are always at the leading level in the industry. Since its establishment, the factory has attached great importance to landscaping, planting grass and trees, and protecting the environment, which has become a common practice. The greening rate of production and living quarters in the factory is over 95%. To this end, the factory won the title of "National Top 400 Afforestation and Greening Unit".
