Concrete silos have four different flow patterns depending on the construction, cone angles, and stored material. These flow patterns dictate how stored material moves through your silo.

 

 

 

 

 

Once a silo begins to lose flow, this accelerates the buildup over time and can lead to additional blockages. While these are the standard flow patterns for concrete silos, the unique shape of concrete domes creates a non-standard flow pater that can increase the likelihood of material buildup. The shape also makes removing said buildup from dome walls and fluidizing equipment more difficult. In both concrete domes and concrete silos, however, once material flow begins to slow, material buildup accelerates and can lead to additional blockages.

 

Proper material flow in silos is important for more than just production schedules. Issues with material flow can cause increased stress on silo walls that may go beyond what the silo was designed to withstand, causing cracking, spalling, wall separation, or structural failure.

 

Proper cleaning and care will increase your silo's useable lifespan and minimize big-ticket repair and cleaning costs. It can also allow you to recover stagnant material that has built up inside the silo.
