Initial Inspection; Shaft Packing Run-In - Precision PMR Rotary Feeder Service Maintenance Manual

Initial Inspection

Before installation, check the feeder configuration and confirm that the proper
configuration has been ordered for your plant.
While the Precision PMR Rotary Feeder is a heavy, sturdy piece of equipment it is possible
for it to become damaged in shipment. Visually inspect the feeder for any damage. We
have found that the drive shaft is particularly susceptible to damage in transport and/or
unloading.
Every Precision PMR Rotary Feeder is carefully checked for proper clearances and
adjustments to the knife, shaft seal, brass seal, and rotor position prior to release from the
factory. Prior to installation, you should be able to move the rotor by hand to check for any
tightness, interference, or ticking noises. Be very careful as the knife is extremely sharp!
If the rotor will not move or if you notice any rubbing noise coming from the either end of
the rotor, it is possible that the rotor's lateral position in the housing may have shifted in
transit. This can be confirmed by inspecting or measuring to determine if the rotor is
centered equally under the eyebrows at each end of the feeder. If the rotor has shifted
position, the rotor must be re-centered in the inlet opening.
This is done by loosening the bearing locking collars and drive coupling, and centering
the rotor in the housing. To assist in moving the rotor you can use a C-clamp large
enough to reach inside of one of the rotor pockets and squeeze from the outside of the
unit until the rotor measures equal distance on both sides of the inlet.
NOTE: DO NOT USE A LARGE HAMMMER TO MOVE THE ROTOR
If you notice a ticking sound when the rotor is turned by hand, the most likely cause is a
shifting of the knife during transport or unloading. See Appendix #4 for instructions on
resetting the proper knife-to-rotor clearance.

Shaft Packing Run-In

After approximately 8 hours of initial operation, the shaft packing seals should be adjusted. See
the instructions in section "Bi-Monthly Service" below.
