Handling wood shavings and sawdust from shaving to barn
The installation is a V-system with a 18m long feeder, lo-
cated underneath 3 cyclones with rotary valves. The feeder
is located on ground level and attached at the bottom of a
vertical conveyor that lifts the material 10m. The vertical
conveyor feeds the top conveyor from below. The top con-
veyor is installed above the roof of the barn with several
outlets. When the barn is filled up to the first conveyor out-
let, the second conveyor outlet will empty the conveyor and
so on. The top conveyor is in total 36m long.
The system is designed to take on a wide range of wood
shavings and sawdust with ATEX 3D internal at a capacity up
to 400m³/h. Frequency inverters are installed for the possi-
bility of adjusting the speed for different recipes and save
the wear liner by not running the conveyors empty.
