Conventional filling
- Wood chips are not distributed optimally in the storage room
- Risk of uncontrolled accumulation and manual correction
Wood chip refuelling systems
Inside ejector
Maximum use of storage room volume
Refuelling systems
With ejector inside
Vertical refuelling system
The fill-up process is made through an inner ejector. This system can be used for storage rooms in upper floors as well as in rooms with no corresponding access. The storage room capacity can be used in an optimal way and there is very little dust distribution. Depending on the nature of the wood chips the ejection range can be between 4 and 5 m and the conveyor capacity up to 50 m³/h
Inside ejector system
Flow path and operating principle
- Vertical auger inside the storage room
- Adjustable ejector with throw range of 4 to 5 m
- Conveyor capacity up to 50 m³/h
- Two fill level indicators in the storage room
- Very low dust distribution during filling
- Optimal use of storage room volume
Conventional filling
- Front loader filling usually requires sufficient access around the storage room
- Material distribution often remains uneven
Conventional filling
- Standard blowing systems can generate higher dust loads
- Useful volume can remain partially unused
Inside ejector
Advantages of vertical refuelling with inside ejector
Total package from Hargassner

Vertical wood chip filling system from Hargassner
Practical filling process
Truck unloading into receiving trough
- Vertical system receives wood chips from truck unloading
- Material is fed continuously toward the ejector
Ejection and distribution in storage room
- Ejector spreads wood chips over a large area
- Even distribution reduces manual intervention
Level monitoring and operating safety
- Fill level indicators protect against overfilling
- Maintenance switch supports safe servicing
