The Fuji King Debarker is an innovative development in debarking technology. The machine utilizes rotary action to create a unique combination of mechanical and log-to-log contact to efficiently remove bark from logs of all shapes and species. The result is cleanly debarked logs with little fibre loss, from difficult and widely varying furnish in all operating conditions.

Features of the Fuji King Debarker include:

• Full contact of rotors along entire length of log ensuring small diameter, crooked and swept logs can be effectively debarked.
• Far gentler action than conventional drum debarkers ensuring fewer damaged logs, less fibre loss and lower operating costs.
• Bark is expelled to a separate conveyor.
• The modular design ensures the system can be sized to fit any application.
• The Fuji King Debarker is the only rotary debarker with inclined abrasive plates, necessary when dealing with tough species and frozen conditions.
• The Fuji King Debarker has been proven in over 200 installations worldwide. This includes 40 systems in North America, many of which are in pulp woodrooms operating 24 hours per day. The King is the only rotary debarker that can make this claim.

• Contact with debarking plates
• Log to log contact

As the rotors turn – they bring the debarking plates into contact with the bark. This contact, along with the log to log contact within the debarking chamber breaks the bond between the wood and the bark at the cambium layer.

Inclined Plate
With other rotary debarker designs, the plate is installed without an incline. In the Fuji King Debarker design, the plate is oriented at an angle to the rotor surface rather than level with the surface. This design optimizes the angle of force imparted onto the log and promotes:

• Optimal individual log rotation exposing more of the bark surface to the debarking plates
• Optimal over-all log rotation within the chamber exposing more logs to the debarking plates

Vector Direction


Bark Expulsion
Loosened bark drops to the waste conveyor beneath the debarker.

Rotor Comb
The Fuji King Debarker design incorporates a rotor comb between and to the side of the rotors. The comb incorporates slots through which the debarking plates pass through as the rotors turn. The benefit of this feature is that the action of the plates passing through the slots forms a slicing action which actually cuts the loosened bark into smaller pieces and forcibly expels it from the debarking chamber – ensuring complete separation of the bark and wood streams.

Plate Profile Aggressiveness
The debarking plate profile can be varied to suit variations in:

• Wood species
• Seasonal variation ( e.g. frozen conditions)
• Wood size and shape
• Freshness

The Fuji/King Debarker design offers six different plate profiles that are bolt-on detachable and re-buildable.

Gate Height
The final control variable is the discharge gate. The gate height is controlled by the operator and has the effect of controlling the wood fill level within the debarker. Raising and lowering the gate raises and lowers the fill level of logs within the debarker.

Advantages of the Fuji King Debarker

• Allows simultaneous processing of a wide variation in species, diameter, length and shapes.
• Proven in over 200 installations worldwide; many North American operations running 24/7.
• Modular design can accommodate plant level capacities in Pulp and OSB applications as well as the single module requirements of woodyard residual clean-up.
