During the production process of using a three tube dryer and a dry powder mortar dryer, the temperature at the tail of the dryer may sometimes change during use. Before this phenomenon occurred, the temperature at the kiln tail was normal, but as the operation time increased, the temperature at the kiln tail gradually increased. Therefore, it is necessary to promptly identify the cause.

If the tail temperature of the three tube quartz sand dryer is low, the possible reasons are:

1. Poor preheating of materials;

2. Low firing temperature;

3. The discharge amount at the tail of the dry mortar dryer is too large

4. Low ventilation inside the dryer:

5. The speed of the dryer is too fast, and the material stays in the dry mortar dryer for too short a time;

6. Poor sealing at the rear of the dryer, resulting in significant air leakage;

7. Instrument malfunction;

8. The formation of circles or large balls inside the dry mortar dryer leads to insufficient ventilation inside the dryer;

If the tail temperature is high, the possible reasons are:

1. High firing temperature;

2. Excessive ventilation inside the dry mortar dryer:

3. The coal pipe is located towards the inside:

4. The feeding amount of the dry mortar dryer is small or the material is cut off;

5. Slow speed of dry mortar dryer:

6. Pre burned materials with high decomposition rate;

7. Instrument malfunction.

The above is the relevant content introduced by the manufacturer of the three tube dryer, hoping to be helpful to everyone.
