Daye Peak Overhaul Technical Transformation Results Showing
News During the Spring Festival overhaul this year, Daye Peak Cement Company carried out a comprehensive technical transformation and maintenance of the production equipment in the factory area. Since 4# August 10 ignition to resume production, the operation effect is remarkable.
Daye Peak Investment ,200 ,000 Yuan has systematically reformed the cement mill. Two cement mills and two warehouses have been changed into three warehouses mills. The grate plate has been replaced with a non-stick ball grate plate to ensure ventilation in the mill. The new material retaining ring has been replaced in the second warehouse to reduce the flow rate in the mill, optimize the layout of the existing frequency conversion fans of 132KW , 90KW and 75KW , increase the ventilation area of large cloth bags of 3 roller press, reform the feeding devices of three roller presses and pneumatic rod valves, adjust the blanking of the cone of the steady flow bin of 1 and 2 roller presses, and reform the technical reform of lithium slag hopper. At present, the work of the three roller presses has been significantly improved. The current of the two storage hoists is more than 5A higher than the best level before the renovation. It is expected that the hourly output will be increased by more than 15 tons. The grinding cement 0.080mm sieve residue can be stably controlled below 2.5% , and the sieve residue of 0.045mm is controlled within 10% . The regulation means is effective, according to the daily report, the power consumption of tons of cement grinding can be reduced by 1.5kwh after the transformation, and the expected transformation effect is achieved overall.
Daye Peak originally adopted the third generation grate cooler of Tianjin Institute. Although it has been upgraded several times in the past ten years, with the increase of kiln output, the cooling effect of clinker is getting worse and worse, which not only affects the thermal power of kiln system and increases energy consumption, but also greatly affects the output of cement grinding table, grinding power consumption and cement quality in the next cement grinding process due to the high clinker temperature. In order to maintain the leading cost and advanced technology in the industry, Daye Peak updated the original grate cooler. The Tianjin Institute's traveling steady flow cooler has the characteristics of good cooling effect and convenient equipment maintenance, and is equipped with the most advanced Halifax cooling fan in the industry. After several days of debugging and operation, the retrofit effect of grate cooler has initially appeared. The clinker discharge temperature is controlled below 120 degrees. The maximum grate bed speed of grate cooler is given 7.5 times / minutes. The fan air volume and grate speed still have a large margin. The bottleneck of restricting the energy saving, high yield and high efficiency of the kiln system has been broken, and the reduction of the temperature of the incoming clinker has also created a prerequisite for the next process of cement grinding to increase production capacity, reduce energy consumption and stabilize quality.
In addition, Daye Peak also shifted the original desulfurization gypsum batching bucket and added a lithium slag mixing batching bucket to increase the amount of lithium slag used to ensure normal feeding, and at the same time, it is also convenient to further expand the variety of mixed materials.

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.
