Feed Tube
The feed tube assembly
consists of two identical feed
tubes stacked on top of each
other. The feed tube is
designed to feed material
directly to the center of the
impeller table. The feed tubes
are interchangeable to extend
the life of each feed tube.
Use the following procedure to
reverse the feed tube.
1. Lockout/tagout all power to
the vertical shaft impactor.
2. Attach lifting chains to the
lifting lugs on the feed box.

upper feed tube. Remove
the rubber seal between the
feed box and the upper feed
tube.
4. Unscrew and remove three
feed tube adjusting rods.
5. Remove both feed tubes.
Each feed tube section
weighs 71 lbs.
6. When re-installing, reverse
the feed tubes so that the
worn feed tube(lower) is on
the top next to the feed box.
Inspect the seals for
damage. Make sure they
are intact.
