Refilling Volumetric/Gravimetric Feeders

Loading a Loss in weight feeder that is operating in a continuous mode requires the right kind of equipment. The objective is to refill the feeder as quickly as possible. Many times the Feeder is purchased without consideration of how the feeder will get filled and refilled.

Refilling Volumetric/Gravimetric Feeders ensures that you process will be completed as fast and as smoothly as possible. Save time, money, and maintenance with these Feeders!



When the feeder reaches a low level signal the discharge valve on the Refilling Volumetric/Gravimetric Feeder will open, refilling the feeder in a matter of seconds. This allows it to operate in gravimetric mode as soon as possible.  Accomplish this by having a charge of material ready in the vacuum receiver at all times.

The Sequence of Events is as Follows:

  • The operator turns on the VAC-U-MAX Control Panel, which is interfaced with the feeder control panel, and then turns on the vacuum source.
  • Once this is done and the material is available at the pick up point (point where vacuum, suction, is available) the vacuum receiver will fill to a high level.
  • The material is immediately discharged into the feeder allowing the feeder to begin dispensing product.
  • The discharge valve on the vacuum receiver will close and more material will be conveyed into the vacuum receiver and held there until the feeder signals a low level mode.
  • The process will repeat itself until all the material has been conveyed or when the operator turns off the control panel.
