When the ceramsite rotary kiln runs slowly, it is easy to form a loop during the operation of the ceramsite rotary kiln. If the loop phenomenon is serious, it will not only affect the thermal system of the kiln, but also affect the ventilation of the kiln, making the ventilation worse, and causing the clinker to roll, come out of the kiln, and smash the kiln skin. There are two types of ceramsite rotary kilns, front rings and rear rings. What are the hazards of the front and rear rings? How to solve them?

The hazards of the front ring of the ceramsite rotary kiln:

The front ring of the ceramsite rotary kiln is not very high, which increases the thickness of the rotary kiln layer, but does not affect the combustion operation, which will prolong the burning time of the material. The front ring is thick, the ventilation of the ceramsite kiln will decrease, and at the same time, positive pressure will appear along the kiln head, the flame will not enter the kiln, and the shape of the flame will become larger. In addition, severe ringing in front of the ceramsite rotary kiln is not easy to spread larger clinker, and the kiln skin is easily damaged.

Given this situation, when handling, do not pull out the coal injection pipe to keep multiple high temperatures in the loop position so that the front ring is gradually burned.

The danger of the rear ring of the ceramsite sand rotary kiln:

Generally, the ceramsite sand rotary kiln is mainly formed between the firing zone and the transition zone, and its formation will affect the ventilation, production and quality of the entire system. To prevent more serious production failures, we usually use the hot and cold alternating method to solve them. When the nodules of the ceramsite sand rotary kiln are long and not high, just pull out the coal injection pipe and adjust the flame shape to reduce the temperature at the rear ring, and then gradually decrease it.

The rear ring is already thick, which seriously affects the ventilation effect of the kiln. This is to reduce the feed rate to 80% of the normal feed rate first, and then use the hot and cold alternating method to burn for 2 hours until the ring is formed. Burn it. In short, the formation of the ring phenomenon in the ceramsite sand rotary kiln is a very common phenomenon. Kangwan Environmental Protection reminds you: This requires us to solve the different conditions of the front and rear rings in the actual production process to better improve the working efficiency and calcination quality of the ceramsite sand rotary kiln.
