Bottom Filling

The bottom filling is used for conveying and storing bulk products without segregation.


The STAG dense phase conveying system, featuring components that have been especially designed to be used in this application, combined with the successful bottom filling method, ensures a gentle transport into and a segregation-free filling of silos.

The bottom filling system is composed of one or several injection points located on the side of the silo body. The filling of the silos is carried out directly into the bulk material bed. Therefore, the system does not require any falling heights, which in turn allows avoiding – or minimising – segregation of the bulk material. For the distribution into the different filling levels, special bulk material diverter tubes are used.
