Recently, Duyun Shangfeng " At present, the central control building and water pump house in the production area of the main project of the cement production project have been basically completed. Kiln head boiler installation, cable bridge installation, clinker hot air pipeline and other equipment are being installed and commissioned, and joint storage, cement packaging, cement storage, cement grinding, transfer station and other production workshops are being completed.
It is understood that," The 4000t/d clinker cement production line reduction and replacement project of Duyun Shangfeng Southwest Cement Co., Ltd. will build a 4000t/d clinker cement production line with 9MW pure low-temperature waste heat power generation and 200t/d sludge disposal system, with an annual output of 1.32 million tons of clinker and 1.7 million tons of cement. The annual power generation (six-stage preheater) is 3432 × 104kWh, the annual power supply is 3174.6 × 104kWh, and the annual sludge disposal is 6.
Building a more competitive clinker line has always been one of the means for cement enterprises to optimize their market layout, improve their competitiveness and seize the leading position in the market.
It is understood that a number of cement clinker production lines are planned to be put into operation in the first half of this year, including Conch, Jinyu Jidong, Queshi and other enterprises.
In addition to being put into operation soon, there are three clinker production lines in China that have been put into operation recently.
Shuicheng Conch 4000t/d Cement Clinker Project is scheduled to be put into operation
in May. Since the construction of Shuicheng Conch 4000t/d Cement Clinker Production Line Project started, the project construction management has been continuously strengthened, while ensuring the quality of the project, efforts have been made to promote the efficient and steady progress of the project construction. The project is expected to be put into operation by the end of May this year. Qin Enmeng, deputy general manager
of Shuicheng Conch Panjiang Cement Co., Ltd., introduced that the 4000t/d cement clinker production line project is located in Shihe Village, Laoyingshan Street, Shuicheng District, with a total investment of 8. After the project is put into operation, it will bring the annual production capacity of 1.2 million tons of cement clinker and 1.58 million tons of general Portland cement to Shuicheng Conch.
Tan Enmeng said that at present, the overall installation project of Shuicheng Conch Project has been completed by about 75%. Now the roller press equipment of the raw material system has been installed in place, the preheater has been installed to the fifth floor, and the overall equipment installation on the kiln has been basically completed. The 4000t/d cement clinker production line of Shuicheng Conch is expected to be ignited and put into operation on May 28.
Panshi BBMG Jidong 4500t/d clinker production line is planned to be put into operation
in April. Up to now, the new 4500t/d cement clinker production line project has completed civil construction and main equipment installation, and is expected to be put into operation in April this year; The project with an annual output of 3 million tons of sand and gravel aggregate has been completed and will be put into operation soon; the project of fly ash storage and deep processing and comprehensive utilization is speeding up construction and is expected to be completed in April. On March 13, the reporter learned from Panshi Jinyu Jidong Cement Panshi Company that the new building materials industrial park project invested by them will be put into operation soon.
project said that at the beginning of the construction of the industrial park, the goal was to be world-class." Apply digital technology to build "unmanned factory". He introduced that the project is planned to invest 3 billion yuan and be constructed in two phases. The first phase of the project is planned as a whole according to the "7 + 4" plan, namely, seven new projects and four industrial upgrading and technological transformation projects. Through the application of new energy and the construction of new infrastructure, we will build a production base of building materials products in the whole industrial chain, which integrates cement manufacturing, new building materials, ecological environmental protection, commercial concrete, modern logistics and other industries. After the completion of the project, It is estimated that the total annual industrial output value will reach 2.4 billion yuan. 7.
Luo Jixiang, general manager of Yangxin 
Ningxia Building Material Qingshui Co., Ltd. was put into operation
on March 10. The 4000t/d second-generation new dry energy-saving, environmental protection and green intelligent demonstration project of Ningxia Building Material Qingshui Co., Ltd. was put into operation smoothly.
projects, The standard is world-class, with a high degree of high-end, green, intelligent to achieve quality and efficiency, to promote Qingshui shares to achieve industrial transformation and upgrading.
At present, Qingshui has realized a 100-person factory, further improved labor productivity, reduced comprehensive power consumption and standard coal consumption of clinker, realized ultra-low emission of pollutants, and effectively consumed industrial waste.
Guangxi 
project is an off-site upgrading and reconstruction project, with a total land area of 1300 mu." A 5000 t/d clinker new dry process cement production line will be built, equipped with 9000 kW pure low-temperature waste heat power generation and cement grinding system, with an annual output of 1.5 million tons of clinker and 2 million tons of cement, including 70% of PO42.5 ordinary Portland cement. PC42. The total investment of the project is 128586.
According to the big data of cement, in 2022, 13 cement clinker production lines will be fired nationwide, with a total capacity of 23.5 million tons, and 47 will be closed, involving a capacity of 29.51 million tons. The actual clinker production capacity at the end of the year is about 1.8 billion tons, a net decrease of 6.02 million tons compared with 2021.
In 2023, it is expected that more than 30 new lines (with a capacity of 44.52 million tons) will be put into operation, but under the poor market environment, it is expected that the production progress will be less than expected, and the total clinker production capacity will decline steadily.
