Tilted floor Pellet store
Only explosion-proof electrical installations
DANGER!
No electrical equipment such as switches, lights,
junction boxes, etc. may be present in the pellet
store.

Unavoidable installations must be airtight and
moisture-proof to protect against explosions, and
in the flight path of pellets they must be protected
against damage. Existing junction boxes that
cannot be installed elsewhere should at least be
filled in with foam to seal all exposed live parts.
6.6 Tilted floor
A tilted floor is needed
The pellet store must have a floor with 40° tilt to ensure
that all pellets in the store can be extracted. This
applies for systems with conveyor screws as well as
for suction heads.
Construction of tilted floor for storeroom
For the slanted floor, three-ply concrete formwork
panels 27 mm thick have proven effective. Unplaned
wooden boards 25 mm thick with a smooth plastic-
laminated surface can also be used.
The slanted 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 the often
statically inadequately dimensioned walls do not have
the strength to withstand the forces involved.
