Daye Peak Adjusts Grate Cooler to Reasonably Control Clinker Temperature
Recently, with the substantial decrease in winter temperature, Daye Peak Cement Company has adjusted the grate cooler equipment according to the production process requirements to reasonably control the clinker temperature. At the beginning of
2020 , the technological transformation of Daye spike grate cooler was completed, and the clinker temperature of the grate cooler was greatly reduced, basically solving a series of process equipment problems caused by the high clinker temperature in summer and the difficulty in controlling the cement temperature of the grind. However, with the arrival of winter, the ambient temperature is greatly reduced, the clinker temperature is low, the moisture content of the mixed material is difficult to control, and the temperature of the roller press system and the mill system is low, resulting in high moisture content of the cement, causing quality fluctuations. In order to solve this problem, Daye Peak adjusted the grate cooler according to the process requirements.
This adjustment controls the air volume of the second-stage fan of the grate cooler to 70% of the original air volume, and controls the air volume of the two air chambers after the first stage to 70-80%. Adjust the ventilation area of the grate plate of the corresponding air chamber, reduce the air volume, maintain the air pressure, and avoid material leakage in the air chamber. At the same time, a small hot stove is added to the inlet air pipe of the roller press V to cope with the normal operation of the mill during the kiln maintenance period. After
adjustment, the clinker temperature control is reasonable, the temperature of the roller press system and the mill system reaches the normal level, the material moisture is taken away in time, the cement moisture out of the mill decreases, the strength loss and the problem of storage shed do not appear again, the working efficiency of the 3# roller press and the fixed roller reaches 85%, and the feeding amount reaches the normal level.

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.
