Foreign ashes are delivered by truck and pneumatically unloaded into four silos. A pressure conveying vessel with STAG rotary valves as inlet and outlet fittings is installed under each silo. The four pressure conveying vessels convey the ashes into two intermediate hoppers which are planned above the ash washing plant. The ash is continuously dosed into the washing process via rotary valves and a screw conveyor.

The coating after the filter process is discharged by TRUMAG screw conveyors and transported into a container.

STAG is responsible for planning, delivery, installation, commissioning and training.
