What should to do if the mechanical lime kiln calcination belt moves up
In the production process of mechanical lime shaft kiln, the upward movement of the calcination belt is a common and significant problem, which can lead to a decrease in lime quality and an increase in energy consumption. Effective measures need to be taken in a timely manner to solve this problem.
Accurately analyze the reasons
The upward movement of the calcination zone is usually caused by various factors. Possible issues with fuel supply, such as excessively large and unevenly distributed fuel particles, leading to insufficient local combustion and abnormal heat transfer; It is also possible that the ventilation system is out of balance, with excessive or insufficient air volume, causing turbulence in the airflow inside the kiln and affecting the position of the calcination zone; In addition, changes in material properties, such as uneven particle size of limestone and fluctuations in moisture content, can also interfere with the calcination process.
Take targeted measures
To address the fuel issue, it is necessary to strictly control the fuel particle size and ensure its uniform distribution, which can be achieved by adjusting the crushing equipment and fabric distribution device. For the ventilation system, it is necessary to accurately adjust the air volume to match the calcination requirements, and at the same time check whether the ventilation ducts are blocked or leaking, and clean and repair them in a timely manner. Regarding material issues, it is necessary to strengthen raw material management to ensure uniform particle size and stable moisture content of limestone. If necessary, pre-treatment of materials can be carried out.
Strengthen process monitoring and adjustment
During the processing, close attention should be paid to changes in parameters such as temperature and pressure inside the kiln, and the position of the calcination zone should be monitored in real time through observation holes or online monitoring equipment. Adjust fuel supply, ventilation, and other operations in a timely manner according to parameter changes to gradually restore the calcination zone to its normal position.
Although the upward movement of the calcination belt in the mechanical lime shaft kiln is a difficult problem, as long as the cause is identified, correct measures are taken, and monitoring and adjustment are strengthened, the problem can be effectively solved and the stable and efficient operation of production can be guaranteed.
