5.2 Fuel extraction with screw conveyor

Pellet extraction screw conveyor, D = 120 mm

For part no., see pricelist
The discharge screw conveyor is used to transport wood pellets from
a rectangular fuel store. The wood pellets trickle via a tilted inter-
mediate floor into the screw conveyor channel. The screw conveyor
located in this channel transports the wood pellets to the outlet.
Standard delivery:
■ Pellet discharge screw conveyor as per project drawing
To be carried out by the customer:
Delivery and installation of the intermediate floor (preferably made of
wood) incl. static calculation and design. The forces resulting from
the weight of the combustion material (approx. 650 kg/m³) should be
transferred through the floor of the fuel store and not through the dis-
charge screw conveyor. Observe this when designing the intermedi-
ate floor.
