Keeping your powder feeder equipment fully operational and in good working condition is essential for business process efficiency and success. Too often, operators are not mechanically skilled or maintenance people are far too busy to keep up so they wait until it’s too late to service their equipment properly. This leads to production downtime with expensive coating rework and increased service costs in the damage of feeder parts.

Here’s what you need to know to ensure your powder feeder is properly maintained:

Your Powder Feeder Needs Regular Maintenance

There are two types of powder feeders, rotary disc powder feeders and fluidized bed powder feeders. Because of the design of each feeder, the repairs and common issues differ between them. However, failure to provide maintenance, regular repairs, on either style will cause the components to endure extended wear, causing them to break. Continuous usage allows build up of powder residue, causing operations to be less efficient. If these problems persist without being inspected and repaired, major equipment repairs at higher costs are more likely to be needed.

Regardless of the type of powder feeders you have, they all require repair service at some point and should be subject to regular maintenance work to return the equipment to optimal condition and reduce the chance of a major repair in the future while doing their job of proper feed rates.

Your technicians should inspect these areas in a Fluidized Bed Style:

  • Plugged filters in the fluidized bed feeder hopper base
  • Electronic pressure regulator failure
  • 20 to 28 psi of supply to this regulator
  • Filter bowl leaks
  • Fitting leaks
  • The correct pickup shaft
  • Replace all seals
  • Leaking circle seal pop off valves
  • CPU failure
  • Failed 3 volt battery in the upper back cabinet
  • Motherboard failure

Your technicians should inspect these areas in a Rotary Feeder style: after 40 – 60 hours of usage.

  • Remove the upper canister and blow clean
  • Remove the rotary disk. If the technician can catch a fingernail on the bottom of this disk, it indicates a worn disk
  • Replace the felt rings and o-rings
  • Inspect the surface ring with the bottom of the powder wheel
  • Replace the dump valve diaphragm

Send in Your Feeders to UTS

Our team is experienced in finding and repairing common or unique issues with your equipment:

  • Rotary feeders and fluidizing style feeders both require a gas-tight canister unit(s) to allow the carrier gas to move the powder suspended in the stream to the gun. Our technicians will check and repair any leaks in this system.
  • The UTS team will ensure that rotary disks are in good condition and that the felts underneath them are replaced after 40 – 60 hours of usage.
  • On fluidized feeders, our technicians will ensure that the fluidizing filter stones are changed. We recommend regular changing as needed, but at least once per year.
  • The UTS team will verify that the correct pickup shaft is being used for the type of powder application and will change it out. We recommend regular pickup shaft changes.
  • The UTS team will verify all solenoid valves in the lower area are not becoming loud with buzzing.
  • The electronic pressure regulator needs to function correctly and smoothly between 0-15 psi. Our team utilizes a pressure transducer for this test to ensure it’s within range.
