Silo Protection Systems Over-Pressure Safety Dust Venting

Silos can rupture, pressure relief valves (PRVs) can blow and, in some cases, filter housings on top of the silo can be ejected from their mounts. Such an incident can result in injury or even death. Furthermore, the powdered product from the silo will escape into the environment, causing pollution.

Powder Storage Silos: Disasters Waiting to Happen ...

Sep 24, 2015  There is strong empirical evidence that many powder storage silos around the world are ‘disasters waiting to happen.’. The practical reality is that silos can split or rupture at pressures as low as 1 or 2 psi above atmospheric pressure. Malfunctioning filter housings can be ejected at similar pressures. “The truth is that merely relying ...
