Pellet store Requirements for pellet store
37
The inclined floor should be flush with the
enclosing walls so that no pellets can fall into the
empty space beneath it. However, the support frame
itself may not lean against the walls since they may not
have the strength to withstand the forces involved.

The inclined floor must withstand the weight of the
pellets (bulk weight 650 kg/m³). Assuming the usual
commercially available formwork panels with a width of
100 cm, members of the support frame should have a
separation of 50 or 100 cm. For these separations, the
following tables show the required beam thicknesses
depending on the room width.
Pad wall opening for conveyor screw trough
Sound from the screw can be transmitted through the
pellet store walls into the house. To avoid that, pad the
wall opening for the troughs with soft material (mineral
wool).
Under no circumstances should the conveyor screw
trough be cemented into a concrete wall without
acoustic insulation.
Small stores with reserve
For small pellet stores, the tilted floor can be truncated.
A reserve of pellets will remain on the resulting flat
surfaces; when the main store is empty, the reserve
pellets can be swept into the main store manually.
The disadvantage of this method is that the reserve
space must be cleared at least every 3 years so that
dust and broken or moist pellets cannot gather.
