Feeding Bridging of CMC
Fenómeno do problema
Material bridges in the CMC hopper and does not flow down, causing extrusion material interruption
Análise das causas
CMC particle shape is irregular and bridges; hopper design is improper with too large cone angle; material contains moisture and agglomerates
Solução
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
Conclusão principal
Bridging is caused by particle characteristics and hopper design; vibrator and hopper modification are the key
