Powder Constant Feeder Model EF/EFS
Feeds any powder materials at a constant quantity
Principle
- The pressure adjust plate provides constant bulk density without influenced by the powder pressure in the upper hopper.
- The impeller acts to fill in the powder into the round U shaped groove.
- The rotating turn table and the scraper allows continuous feeding.
- The model EFS has reduced adhesion by the installed Oldham mechanism, which creates eccentricity movement of the table and the impeller.
Features
- Feeding at a constant quantity in high-precision
- Applicable to adhesive powder or highly flowable powder
- Capable to feed at a constant quantity regardless a capacity of a connected hopper.
- No flushing and blocking
- No pulsating flow of the particles during feeding.
