  • Separation of dirt and bark from wood chips

Preferably the chips entering the cylindrical screen are blown into engagement with an impact plate to aid in disloading particles of dirt and bark from the chips. The chipper may be mounted on the same trailer or may be a separate trailer-mounted unit.
