Sichuan Ya'an Southwest Cement Co., Ltd.: Aiming at Details and Targeted Efforts to Do a Good Job in Reducing Costs and Increasing Efficiency

Southwest Cement , takes cost reduction as its grasp and efficiency as its goal, actively carries out excellent cost reduction work from a detailed and small point of view, continuously strengthens management and control measures, aims at the target by means of cost control, repairing the old and utilizing the waste, and extensively excavates the cost reduction space in all links and fields. Do a good job of reducing costs and increasing efficiency in an all-round way. According to the requirements of Southwest Cement on "Tamping Basic Management, Excellent Cost Reduction 2023, Enhancing Enterprise Competitiveness" and the actual situation of the company, the Southwest of Ya'an,

Sichuan Province, has formulated the implementation plan of Excellent Cost Reduction, and has refined the sub-projects of the whole year's plan one by one, defined the time nodes, and formulated the plan. Implement the division of responsibilities. The company has set up a working leading group with the general manager as the group leader and the heads of departments and offices as members, leading all employees to focus on the objectives and tasks, work hard, vigorously create a strong atmosphere for entrepreneurship, and make great efforts in power, fuel and maintenance costs, successfully setting off a wave of cost reduction and efficiency enhancement.

First, we should comprehensively promote the pre-maintenance management of equipment, and make a regular inspection plan for equipment by means of three-level patrol inspection and professional inspection of third-party equipment, so as to ensure the stable operation of equipment and zero accidents in safe production. The second is to continuously optimize the operation parameters of the vertical mill, adjust the height of the baffle ring and the area of the nozzle ring according to the existing material characteristics, increase the outlet sectional area of the vertical mill, reduce the resistance, gradually reduce the speed of the circulating fan and the current of the main mill, so as to reduce the power consumption of the raw material process. Thirdly, a series of measures, such as checking and replacing the pipelines and valves of the surplus power system one by one, cleaning the condenser and optimizing the windbreak wall of the grate cooler, have increased the power generation year on year. Fourthly, by replacing the circulating fan of cement mill, adjusting the gradation of cement mill, optimizing the V-selection discharge port and optimizing the system operation parameters, the comprehensive power consumption of clinker and the power consumption of cement process decreased year on year. The

first is to optimize the position of the dividing wheel of the preheater and the position and angle of the spreader boxes at all levels of the preheater during the Spring Festival overhaul, so as to improve the material dispersion effect and heat exchange efficiency. The second is to optimize the inlet of the preheater cyclone, increase the air deflector, change the internal flow field of the cyclone, and improve the separation efficiency and heat exchange efficiency of the cyclone; the third is to stabilize the coal source, and use one kind of coal source in one kiln opening cycle to ensure the stable operation of the system; the fourth is to stabilize the raw meal proportioning through the reasonable collocation and regulation of the calcareous waste residue, and the standard coal consumption per ton of clinker of the Company decreased year on year. The

first is to adopt the training mode of "please come in + go out", invite experts to the company to carry out skills training, and send 45 employees to brother enterprises for follow-up study, so as to continuously improve their skills and technical level. The second is to formulate an incentive mechanism for rationalization proposals, encourage the whole staff to participate in the rationalization proposals for cost reduction, organize regular monthly review meetings for rationalization proposals, select proposals beneficial to the company's cost reduction for discussion, and use maintenance time for implementation; Thirdly, a series of minor reforms have been carried out successively, such as the optimization of C5 feeding pipe of preheater, the optimization of the position of the feeding box, the optimization of the nozzle ring of the vertical mill, the resistance reduction of the vertical mill separator, and the optimization of the steady flow bin of the cement mill, which have greatly reduced the maintenance cost of the company.

Reduce costs, increase efficiency, promote leapfrogging, and pursue excellence. Sichuan Ya'an Southwest will continue to adhere to the management concept of "saving one point is not too little, wasting one point is more", regularly and continuously carry out excellent cost reduction and efficiency enhancement work, while striving to reduce the cost of equipment operation, continuously and effectively improve the efficiency of equipment work, laying a solid foundation for the company to successfully complete the annual target task.
