Problem: Agglomeration formation
| Cause | Remedies |
|---|---|
| Grain distribution too fine. | Contact the powder manufacturer. |
| Humidity in the powder due to incorrect storage. | The powder must be dry and stored at the working temperature. |
| Sintering in the nozzles caused by a too high Total air pressure. | Reduce the Total air pressure to 4 – 5 Nm3/h. |
| Poor fluidization in the powder container caused by humid compressed air or a clogged fluidizing plate. | Check the compressed air for cleanliness, replace the fluidizing plate. |
