Silo filling

Filling silos via horizontal intake and a vertical conveyor — in service in plants over 20 metres high.

Silo filling — Wildfellner conveying system in service

The layout matches bunker filling: horizontal intake via a trough conveyor with hopper, then the vertical conveyor up to just below the silo roof.

The difference lies in the discharge geometry. A silo wants to be filled evenly, otherwise cones form that reduce the usable volume and bridge during discharge. We therefore match discharge height and direction to silo diameter and bulk material.

We have built plants over 20 metres high several times. Depending on the material, the vertical conveyor works in pull or in push mode — a decision made during design that largely determines how smoothly the system runs.

  • 01

    Even distribution

    Discharge geometry matched to silo diameter and bulk material, so the usable volume is right.

  • 02

    Pull or push

    The operating mode of the vertical conveyor follows the material.

  • 03

    Enclosed routing

    Low dust even with dry, fine material.

Further tasks from Biomass

  • Bunker fillingMaterial taken from the intake hopper and conveyed vertically into the bunker — up to 28 metres with no transfer station.
  • Moving floor dischargeTaken from the hydraulic moving floor across the full width of the store and passed on to the downstream system.
  • Pellet screw and pellet conveyorMoving finished pellets from the store or big bag to the boiler — and, in a pellet mill, conveying within production itself.
