Pressure reduction in silos

Intermediate cones a reliable option

If, for whatever reason, a company invests in larger silos, it must be aware of problems. The bulk material experiences greater pressure in a larger silo. This means that the properties of the bulk material change in a negative way. It is therefore very important to keep that pressure under control. An important instrument is the wall of the silo. One can apply rings or coat the wall. This article deals with the application of intermediate cones. With a well-designed intermediate cone one can reduce the pressure, the product flows again, and shocks will be a thing of the past.

Segregation mechanisms: the basics of de-mixing

Behaviour of bulk solids, mechanisms behind segregationn

If samples taken from one batch have a different composition, this is called segregation or de-mixing. The samples may differ on the basis of the components present (different products) or the fractions present (different particle sizes). Segregation means that the properties of a batch of bulk material are no longer constant at every location, resulting in a loss of quality. Combating segregation involves many aspects.

Demixing behaviour and segregation problems in silos

Behaviour of bulk solids, mechanisms behind segregation

In silos segregation of bulk solids that consist of different fractions or component scan be a problem. De-mixing will result in a unsteady composition of product flowing out. At one stage this may be too coarse, at another to fine. Or the percentage of a components is too high or too low. Segregation can occur during filling, during storage and during discharge of the silo. However, in all three stages, measures can be taken to combat this phenomenon.
