How does the phenomenon of rotary kiln running raw materials occur?

 

    1. The amount of raw material feed is uncertain, the amount of coal used is less, the heat consumption control is lower, and the calcination temperature is not enough;

 

    2, the ring or a large number of kiln skin collapsed, the raw material amount suddenly increased, the coal consumption and kiln speed were not adjusted or judged incorrectly;

 

    3. The amount of coal used in the decomposition furnace is too small, the decomposition rate of the raw material of the human kiln is low, the coal used in the kiln is large, but the ventilation in the kiln is not good, and the temperature of the firing zone cannot be raised;

 

    4. The output of the rotary kiln is running in a low range, causing frequent collapse of the preheater system;
