Rotary Feeder Rebuilding

Precision’s customers are sometimes surprised to learn that we have an active business rebuilding rotary feeders.  In fact, we’ve been rebuilding feeders for 20+ years and many of our customers find a feeder rebuild to be an economical alternative to purchasing a new feeder.

Evaluation Process

  • In most cases, customers send their feeders to us for evaluation but our sales team can issue a “standard rebuild” budgetary quote sight unseen.
  • The process starts with the complete disassembly and inspection of the feeder. We document its condition in photos and measurements.
  • A detailed report is prepared and sent to you with a quotation for the rebuilding.

There is no charge for the evaluation process

Rebuilding Process

  1. A thorough sandblasting of all components
  2. The feeder barrel is bored to a “clean-up” diameter that leaves a smooth, sound barrel and removes any remaining chrome plating
  3. The barrel is then re-plated with industrial hard chrome
  4. While the barrel is being reconditioned, the rotor undergoes a process called “ringing and vaning”
    • The rotor vanes and rotor ends are cut back 3-6” from the OD
    • Laser-cut, replacement steel is welded in place to bring the OD back to an oversized dimension
  5. After the barrel is re-plated, the new barrel diameter is carefully measured and the rebuilt rotor is machined to restore the factory clearance for the size of feeder and the operating temperature.
  6. The feeder is reassembled with refurbished end bells, new bearings, new brass seals, new knives, painted, and test-run
