| 1. |
The risks of the bulk material properties are underestimated
|
| 2. |
The wrong silo geometry creates "dead zones" where the bulk material remains motionless, its fine particles solidifies and it adheres to the silo walls
|
| 3. |
Because of the cakings a shaft is formed which only allows funnel flow
|
| 4. |
The funnel flow causes a demixing (segregation) of the bulk material and creates additional cakings
|
| 5. |
The First-in-first-out-prozess does not take place
|
| 6. |
The force of gravity alone or other technical measures can not activate the bulk material
|
| 7. |
The increasing cakings may finally reduce the outlet cross section and lead to a bridge formation
|
| 8. |
The size of the outlet and the speed of the following bulk conveyor determine the discharge volume just passively and hardly variable
