6.13 Fuel discharge by means of funnel discharge
Funnel discharge
Material discharge for round silos is carried out with an agitator inte-
grated in the discharge casing. In its centre, the discharge screw is
driven via a solid universal joint. When the silo is full, the screw con-
veyor moves into a vertical position. The funnel limits the angle of the
screw conveyor when the silo is empty. Drive is via a spur geared
conveyor motor to the agitator. In the case of material compression in
the discharge casing, as a result of increased drive power consump-
tion, the supply direction of the screw conveyor is changed automati-
cally for a period set at the factory. This releases the compression,
preventing a fault.
