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)

Daye Peak Declared 4 Invention Patents Last Year
In 2019, Daye Jianfeng Cement Company changed its thinking, actively explored and tested the use of new materials, and summarized the research results in a timely manner, and successively declared 4 invention patents. In the production process of low-alkali cement, Daye Peak changed the traditional scheme of using high-grade sandstone ingredients alone to replace part of the sandstone and part of the iron correction material with iron ore waste soil, which not only controlled the alkali content in the clinker, but also increased the Al2O3 content in the clinker, ensuring the easy burnability and high early strength of the clinker. Innovation has also been made in the raw material batching scheme, breaking the original high-grade and low-grade sandstones used together and changing them to separate batching of high-grade and low-grade sandstones respectively, thus avoiding the disadvantage of easy material segregation in the process of high-grade and low-grade sandstones used together. At the same time, the original four-component batching is changed to five-component batching, so that low-alkali clinker can be freely switched, which is convenient for production organization and production cost. On the basis of a series of innovative achievements, Daye Peak declared four invention patents in 2019: "a technology for producing clinker from gas sludge and dust collection in steel mills", "a method for treating sludge in machine-made sand mills", "an improvement in raw material batching method" and "a technology for producing low cement from iron ore mining waste soil", all of which have high practical value.
