Reasons for Temperature Changes at the Tail of Dry Mortar Dryer and River Sand Dryer

1. Poor preheating of materials
2. Low firing temperature
3. Excessively high discharge rate at the dryer tail
4. Insufficient ventilation inside the dryer
5. Excessively high rotation speed of the dryer, resulting in an overly short residence time of materials inside the dry mortar dryer
6. Poor sealing at the dryer tail with excessive air leakage
7. Instrument malfunction
8. Ringing or large ball agglomeration inside the dry mortar dryer, leading to insufficient internal ventilation

Possible causes for high tail temperature are as follows:

1. High firing temperature
2. Excessive ventilation inside the dry mortar dryer
3. Burner pipe positioned too far inward
4. Insufficient feeding rate or material cut-off at the dry mortar dryer
5. Low rotation speed of the dry mortar dryer
6. Good preheating of materials with a high decomposition rate
7. Instrument malfunction
