Since entering the factory for internship in 2009 , Liu Haihua has been in Daye Peak for 13 years and has changed his status several times. He has served as a central control operator, on-site monitor and production supervisor. In 2019 , he has also served as a cement mill process supervisor in "to " . Cement grinding is the last process of production. Since then, the information of unsatisfactory output, urgent inventory and high loss of product temperature has become the problems he often faces at work scheduling meetings, which often makes him nervous and determined to change.
Although Liu Haihua graduated from the major of inorganic non-metallic materials, he had to start everything from scratch after he switched to the cement mill process. It is conceivable that he did not adapt. In order to enter the normal working state as soon as possible, he and the cement mill operator groped for the change rules of the output, specific surface area and cement temperature at the mill every day, and modestly asked the craftsman how to adjust the grading of steel balls in the mill. In order to get the first-hand original data, he drilled into the mill for material sampling, checked the main grate plate of the ball position, and went down to the V selection and steady flow bin to check whether the scattering plate and buffer platform, sampling at irregular intervals in the material return pipe to see if the powder selection efficiency is reasonable ... During that time, Liu Haihua spent the longest time in the cement mill, and he was also the dirtiest in his work clothes. Through half a year's efforts, the economic indicators of the cement grinding system have reached or exceeded the best level in history. However, Liu Haihua knew in his heart that this was never enough and was still far from meeting the market requirements. In
2020 , Liu Haihua took advantage of the opportunity to attend the cement technology exchange meeting in Nanchang and Shandong, consulted a number of top grinding experts in the industry, referred to the successful cases of excellent grinding enterprises, and combined with the actual situation of the company, put forward the technical renovation plan of changing two warehouses to three warehouses for cement grinding, optimizing the V selection blanking pipe, and took advantage of the Spring Festival overhaul opportunity to implement. After the transformation was completed and put into operation, the average hourly output of the two cement mills increased by 20 tons, and the cement temperature of the mill was effectively controlled, and the cement performance was also significantly improved.
In the two years since the new coronary pneumonia epidemic continued to affect, the technical transformation of Daye Peak has not been relaxed, and Liu Haihua has not been free. In 2020 , in addition to the technological transformation of production improvement, the cement mill process also carried out the technological transformation of lithium slag use, which not only eased the procurement pressure, reduced the cost of raw materials, and improved the grindability of cement. 2021 , the technical transformation of slag hopper was completed, and wet slag was used instead of high-priced fly ash to relieve the procurement pressure while ensuring sufficient supply of active mixed materials for cement mills, it also created conditions for the later exploration of new low-cost replacement of raw materials ... Through this series of transformation measures, the economic and technical indicators of the cement mill, such as the hourly output and energy consumption, have been continuously optimized, laying the foundation for the full release of Daye's peak production capacity and the further expansion of the market. Daye Peak 2021 sales increased significantly, cement mill series of technical changes played an important role.
At the same time, 2021 Daye Peak Cement Mill Process also carried out post merger, the original mill post and feeding post combined into one, to achieve the purpose of reducing staff and increasing efficiency.
2022 Liu Haihua is still very busy. In the recent Spring Festival overhaul of 2022 , he proposed to replace the cement grinding lining plate with a new type of 5 wave ultra-thin lining plate 3 circulating fan. At present, energy saving and efficiency improvement have been implemented. After picking up the beam in the cement mill for several years, he also mastered a lot of "magic weapon " : using the experimental data of the small mill to adjust the grading of steel balls, using the data of the particle size analyzer to adjust the working conditions of the mill, and minimizing process accidents through curing process parameters and regular process inspection, etc. Of course, there is no end to progress. Liu Haihua has also set himself the next "small target " , that is, the power consumption of tons of cement grinding reaches the level of GB16780-2021 . Therefore, the technical transformation of 4# roller press to improve production and reduce consumption has been listed in his schedule.
In the eyes of colleagues, Liu Haihua is not talkative and even a little dull, but he must do well what he looks. In Daye Peak for more than ten years, he has grown up step by step with the development of the enterprise. He said, "Company has given me a platform for growth, and I will also contribute to the development of the company through my own efforts " . (Wang Yiyan)

"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.
