Peterson 4800F Chain Flail Debarker

Overview

Continuing Peterson’s long history of innovation, the 4800F Chain Flail Debarker is the 6th generation design and has all the features that clean chip operations demand.

The Peterson 4800F Chain Flail Debarker multiple log delimber/debarker is designed to be used in tandem with whole tree chippers to produce high quality pulp chips. Capable of processing multiple logs from 2 to 23 inches (5–58 cm) in diameter, the 4800F increases productivity while reducing bark content, product handling time, and fiber loss.

The 4800F Chain Flail Debarker features upper and lower flails, direct drive lower in-feed and out-feed rolls, and a floating direct drive upper feed roll. The high capacity bark pusher has been redesigned and is now 5 feet (1.5 m) wide.
