What is the Principle of a Centrifugal Feeder?

The working principle of a centrifugal feeder can be summarized in the following core steps:

1. Rotation Generates Centrifugal Force

• Process: Parts are loaded into a stationary outer bowl. A motor-driven rotating disc at the center spins. Friction between the disc and the parts causes them to move.
• Core Principle: The rotation generates strong centrifugal force, which pushes the parts outward toward the bowl’s rim.

2. Part Lifting and Separation

• Process: At the disc’s rim, a ramp or spiral track lifts the parts upward and separates them from the bulk supply below, driven by the continuous centrifugal force.

3. Combing and Orienting

• Process: Parts at the top pass through a stationary combing ring or tooling. This mechanism:
  • Removes Overlaps: Knocks down stacked parts back into the center.
  • Corrects Orientation: Allows only properly oriented parts to pass.
  • Controls Flow: Ensures a single file of parts exits.

4. Orderly Discharge

• Process: Oriented, single-file parts are gently discharged onto an output track.

In summary, a centrifugal feeder uses rotational centrifugal force as the primary driving force to push parts outward and upward, combined with stationary tooling for sorting and orientation, achieving highly efficient and gentle parts feeding.
