6800 Chain Flail Debarker

6800 Chain Flail Debarker

Overview

The Peterson 6800 Chain Flail Debarker is a dedicated chain flail debarking machine designed for long-stem chipping operations that require low bark or ash content.  

Designed for multiple stems, or trees up to 30-inches (76 mm) in diameter, the 6800 quickly and effectively debarks even the hardest feedstock.
The fully enclosed Caterpillar C18 engine rated at 765 hp (570 kW), has the power to drive the 3 fail drums. A 4th flail is also available as an option. The two lower flails are fixed in location, and the upper flails float to match log diameter. The 10-link flail chain is easily replaced through access doors.

The large 60-inch (152 cm) wide, by 30-inch (76 cm) tall feed opening makes loading the 6800 Chain Flail Debarker easy.

Two floating feed heads, and five fixed lower feed rolls control the log through the debarking chamber, and two rolls assist the stems to exit the machine. The massive bark pusher removes the debarked debris to the side of the machine and can be configured to exit on either side depending on the needs of your operation.

The 6800 Chain Flail Debarker is controlled by an IQAN operating system, which provides the operator with all critical engine and performance parameters. When paired with the Peterson 6910, the operator can control both machines.

Features


Easy-to-Service Chain Flails and Replaceable Wear Liners

Upper and lower chain flails strip bark and limbs from the stems, replaceable UHMW wear liners protect the flail housing sidewalls.


Powerful Gear Boxes

The 6800 utilizes high torque gearboxes to drive the upper and lower chain flails—providing 30% more torque than the previous model for efficient bark and branch removal.


High Capacity Bark Pusher

The Bark Pusher has a 12’ x 24” wide opening  with a 10 second stroke moves the bark and limbs efficiently from the debarking chamber.
