Feeding Bridging of CMC
Problembeschreibung
Material bridges in the CMC hopper and does not flow down, causing extrusion material interruption
Ursachenanalyse
CMC particle shape is irregular and bridges; hopper design is improper with too large cone angle; material contains moisture and agglomerates
Lösung
1)Install vibrator on the hopper to break bridging; 2)Reduce hopper cone angle to <30°; 3)Dry raw material to prevent agglomeration; 4)Forced feeding screw
Wichtigste Erkenntnis
Bridging is caused by particle characteristics and hopper design; vibrator and hopper modification are the key
