Bridging
Bridging will happen when a static balance occurs between the internal friction in the silo ans the load applied by the product being stored. |
Mass-flow : it refers to the emptying of the silo without any segregation. It ensures all the particle of varying sizes move down the silo at the same rate. Mass-Flow is often referred to as FIFO or "First In, First Out" principal.

Negative Pressure
Negative Pressure : it happens when a chimney or "rat hole" collapses within the silo. Often, the vacuum relife valve or filter does not have time to act.
|
Chimney
Chimney is located on the longer slope. This phenomenom often happens when the silo is not equipped with Bin Activator or is equipped with a too small Bin Activator.
|
Crash down
Crash down : it occurs when the existing chimney collapses and product falls to the cone section of the silo causing extreme loading and possible damage.
|
Overpressure
Overpressure is either caused as a direct result of product "crash down" that may let it to behave flushing.
|
Flushing
Flushing : when a powder behaves as a liquid. This phenomenom may be the result of a crash down which allows the product to be aerated.
