A chain flail debarking apparatus including a flail chamber accommodating at least first and second rotatable flail shafts being supported on a movable flail assembly framework, and both of the first and second rotatable flail shafts having a plurality of chains, a disc chipper for receiving the debarked logs and trees from the flail chamber and generating wood chips having a desired shape and size, and a single drive for driving both the disc chipper and at least the first and second rotatable flail shafts in the flail chamber. A pivotable feed roller is located adjacent an inlet to the flail chamber for sensing a diameter of the logs and trees to be debarked and moving the movable flail assembly framework, relative to the base frame, so as to maintain the logs and trees being debarked in the flail chamber, substantially centered with respect to both the first and second rotatable flail shafts so that both upwardly and downwardly facing surfaces of the logs and trees being debarked are substantially equally treated.

A debarking drum (1) for the debarking of wood (2) has an essentially horizontal cylindrical drum (10) supported to revolve around its longitudinal axis. The drum has a first end (12) and a second end (14) with an inner surface with inwardly projecting longitudinally extending debarking iron sections (16). Bark openings or slots (20) extend through the drum inner surface (18) and multiple rigid studs (22) protrude inwardly from the inner surface (18) and are positioned between the debarking iron sections (16). The studs operate to break the bark (3) of the wood (2) for debarking. The studs (22) are positioned along a partial length (L) of the drum (10) between the first end (12) and the second end (14). The invention also relates to a method and system for the debarking of wood by the debarking drum.

Disclosed herein are embodiments of batch-style bottom-discharge rotary debarkers for removing bark from a batch of logs in a bin and discharging debarked logs from a bottom of the bin. In some embodiments, the bin includes four walls and an opening in its bottom. In some embodiments, the debarkers include a plurality of rotors, a plurality of chutes, and a plurality of conveyor belt systems for carrying bark and logs away from the bin. In some embodiments, the debarkers include an internal gate which can be moved between a debarking configuration and an unloading configuration.

A rotary log debarker comprising a container. The container comprises a bottom part, two opposed longitudinal walls extending upward from the bottom part, one end wall, and a chute. The bottom part comprises rotors being drivable by a power source. The rotors comprise a plurality of debarking plates. The debarking plates comprise an abrasive surface. The rotary log debarker is characterized in that it is provided with a tilting system for adjustable tilting of the container about a pivot point.
