Daye Peak Two Retrofits Show Effective
News Daye Peak Cement Company carried out grate cooler frame reinforcement and kiln tail fan energy-saving renovation during the Spring Festival overhaul. Although there is only a short period of more than two months of actual operation, it has already produced obvious results. The
Daye Peak Grate Cooler was originally designed to match the production capacity of tons of cement clinker per day. Due to the heavy production tasks in recent years, some parts of the Grate Cooler were damaged due to overload work, which had to be shut down urgently. For this reason, during the overhaul of Daye Peak, the movable frame, inner support wheel support beam, support wheel support, clamping device, support pipe beam and other important components of each section of the grate cooler were unified and strengthened to meet the new operation requirements of the production line.
According to introduction, if the downtime of the kiln system caused by the grate cooler failure is reduced by 75 hours, it is equivalent to recovering the cost of this renovation. Two months after the end of the transformation, the grate cooler has been running smoothly and reliably. After inspection and confirmation during shutdown of 4 months, all components are in normal operation. After the failure rate of grate cooler is reduced, it will not only greatly reduce the workload of employees, but also reduce the labor and material costs when overhauling the grate cooler, and will also play a positive role in promoting the implementation of the "large inspection system.
Daye peak high temperature fan since the establishment of the factory is a conventional centrifugal fan, is the use of high-frequency chopper speed control. With the increase of kiln output, the fan shows some disadvantages. It cannot adjust the speed according to the requirements of the process. The maximum speed can only be controlled at about 850 revolutions per minute. The air volume can only be pulled at full speed by the tail row, resulting in the loss of the tail row's own energy. For this reason, Daye Peak decided to carry out high-efficiency and energy-saving technological transformation of high-temperature fans. According to the plan, the energy-saving transformation of the kiln tail high-temperature fan will be divided into two steps, which will be implemented during the overhaul and medium repair respectively. The first step is to replace the original conventional fan with a high-efficiency and energy-saving centrifugal fan, and the second step is to change the motor control from the original high-frequency chopper control to high-voltage variable frequency speed control.
During the Spring Festival overhaul, the energy-saving transformation of the high-temperature fan successfully completed the first step. Compared with the data of the same period in 2016 , although the power consumption of the high-temperature fan itself has not changed significantly, the power consumption of the tail exhaust fan per ton of clinker is reduced by about 1.3 kW hours, which can save more than ,150 yuan per year, and the renovation cost can be recovered in less than one year. If the second step of transformation is continued during the medium repair period, the energy consumption of the tail exhaust will be further reduced, and the energy consumption of the high-temperature fan itself will also decrease. It is expected that the technical transformation cost will be recovered in two to three years. This transformation not only achieves the expected effect, but also further reduces the production cost and improves the market competitiveness of peak cement. (Du Yuwen Shi Zhangliang)

"Cement Economy 50 People Forum" Jiang Xiaomeng Talk about the Future Development of Cement Industry
On March 14, the "Cement Economy 50 Forum" hosted by China Cement Network was held in Hangzhou, inviting 50 influential economic figures in the cement industry to discuss the future development of China's cement industry. Jiang Xiaomeng, chairman of the group company, was invited to attend the forum to discuss the development of the cement industry with his peers. The theme of this forum is "strengthening confidence, seeking breakthrough, and promoting development". It aims to point out the disadvantages of "mud", actively provide suggestions for the competent departments, enterprise transformation and upgrading, strategic and tactical decision-making in the difficult period of the cement industry, and provide new think tank opinions and methods to help form a new cement economic ecology. In the context of the sharp decline in demand, the cement industry is trapped inside and outside, how to revive the glory? How do cement companies survive and develop next? Around these two topics, the guests at the meeting had a heated discussion. Jiang Xiaomeng pointed out in his speech at the forum that the development of any enterprise is inseparable from the healthy development of the industry. Only when the industry is good can the enterprise be good, and the interests of the industry are greater than the interests of the enterprise. In addition, the competition of similar enterprises should seek a breakthrough from the differentiation, and it is unreasonable to blindly pursue low prices. Industry synergy, industry synergy, supply, demand, price, to find a common price line, on the basis of competition and cooperation, from the management services, cost control and other aspects to highlight the advantages of enterprises. The participants reached consensus on many issues after heated discussions. It is generally believed that 2022 is the most complex year in the cement industry in the past decade, affected by the multi-point spread of the epidemic, real estate downturn and other factors, the cement market demand is sluggish, the contradiction between supply and demand is prominent, prices are falling rapidly, business difficulties, the pace of steady growth of the industry is blocked. Entering 2023, under the macroeconomic situation of stabilizing the economy and promoting development, as well as various regions stepping up efforts to promote the construction of major projects, cement demand is expected to increase in 2023 compared with 2022, and the situation in the second half of the year will be better than that in the first half. However, under the expectation of restorative growth in demand, the cement industry is still facing uncertainties such as continued bottoming of real estate, high energy costs, and overcapacity. In this regard, we should resolutely maintain the normal order of the industry, make concerted efforts to help the industry get out of the predicament, and firmly implement staggered peak production. Through mergers and acquisitions, carbon quotas, energy efficiency indicators, environmental protection indicators, coal indicators, market competition and other means to further resolve the contradiction of overcapacity, optimize the industrial layout, and adhere to innovation-driven in digital, intelligent and green development, so as to promote and finally realize the high-quality development of the cement industry.
