In normal production, the raw material feeding amount is micro-microwave moving, sometimes the equipment will have some problems, or affected by the rainy season, the raw material moisture will change, and the raw material will be agglomerated, resulting in poor material feeding, the fluctuations are relatively large. In this case, the operator is required to observe and adjust frequently, and also has certain predictability and make measures in advance. Reduce the impact on production, quality and equipment.

When there is less material, it is forbidden to extend the coal injection pipe, open the exhaust air, and lengthen the flame. This will cause the temperature of the kiln tail to rise sharply, and the temperature of the decomposition furnace and the cyclone will rise rapidly, resulting in a cyclone. The tube or the blanking pipe is bonded or even blocked.The kiln tail chamber and the decomposition furnace are also easy to crust, which increases the resistance of the system. At this time, the coal injection pipe should be appropriately removed, the small exhaust gas should be shut off, the coal supply volume of the decomposition furnace and the kiln head should be reduced, and the kiln tail should be controlled. The temperature and the temperature of the cyclone are short-burned and the material is returned to normal.

When there is more incoming material, there will be positive pressure in the rotary kiln head. The temperature of the cyclone outlet and the decomposition furnace and the temperature of the kiln tail will drop sharply. At this time, the kiln speed should be reduced appropriately, the feeding amount should be reduced, and the exhaust air should be opened, injecting the coal pipe, which can increase the temperature of the kiln tail and enhance the pre-burning effect.At this time, coal can be added appropriately, but it is not easy to be excessive. It is wrong to add more coal at this time, because this will cause a reducing atmosphere and lower the temperature in the kiln. When the material is used for a long time, there is also a lot of exhaust gas, which does not increase the temperature.When the current of the main motor of the kiln drops rapidly, the speed of the kiln is lowered, the coal pipe is withdrawn, and the air volume is appropriately adjusted. At this time, the short flame is used to make it return to normal. When the working conditions in the kiln are normal, the feeding is carried out.
