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)

The company requires to do a good job in summer safety production
The high temperature season is approaching, and the group company issued a notice a few days ago to make arrangements for safe production in summer. The notice requires all subordinate units of the company to attach great importance to the work of production safety in summer, and all production and business units should hold a special meeting on production safety in summer. According to the characteristics of production in summer, they should focus on safety risk analysis for mines, outdoor operations and high-temperature posts, and implement control measures to avoid the occurrence of safety accidents such as scalding, heatstroke and electric shock. In order to further strengthen the safety production management in the high temperature season, the notice requires the main person in charge of each production and business unit to lead a team to conduct a comprehensive inspection of the production and business premises according to the characteristics of summer production; strengthen the daily safety production inspection of key posts and special posts; timely rectify the found unsafe behaviors and hidden dangers; Strengthen the management of the storage and use of flammable, explosive, dangerous chemicals and drugs; cooling measures shall be taken for the space exceeding the storage temperature limit of articles. If it is found that the electrical equipment circuit and exhaust fan circuit are aged and damaged, replace them in time and keep the grounding wire in good condition. Do a good job in checking the fire pool, pipeline water pressure and fire extinguishing equipment to ensure that the fire fighting facilities are sensitive, intact and reliable. The high temperature in summer is also a period of frequent occurrence of heatstroke and other diseases. The notice requires all units to do a good job in heatstroke prevention and cooling, implement various relevant measures, and equip necessary cooling facilities or materials such as fans, air conditioners, ice cubes and other cooling facilities or materials according to the conditions of the production site; do a good job in the distribution of heatstroke prevention drugs, supplies and cool drinks in workshops, warehouses, construction sites and other production lines; strengthen canteen management to prevent food poisoning.
