Raumaustragung für Kleinsilos

Room discharge

with arm hinges

Is a smaller device for biomass discharge (wood chips or similar materials or something similar to 250 Kg/m³) from at-grade or higher rooms or smaller silos up to Ø 5,6m with fill heights of up to 7,0 m It is a component for the automatic feeding of furnaces (central-heating boilers).

The individual arm pieces are pre-stressed, fitted with spikes and bend at the bearing points. In the filled silo the arm hinges lie under the cap plate. The material is almost exclusively removed through the diagonal open screw conveyor.

Installation angel lower than 10° for best physical extraction Operation!


Wall covering: Wood/sheet metal, if the effective rotation circle of the arms is larger than the width of the silo.
