Features: CBI demo unit that is in great shape (call for pricing). CBI’s three-flail design provides optimum contact with wood to deliver maximum debarking action. It consists of two 50” swing diameter (1.27 m) top flail drums X 48” wide (1.21 m) with 11-link chains and one 40” swing diameter (1 m) bottom flail drum with 8-link chains. The inside of the flail chamber has replaceable wear liners for easy maintenance and overall longevity of this machine. Residue is discharged from the flail chamber by a large hydraulically-actuated push ram that utilizes a 5 1/2” bore, 90-inch stroke cylinder.
