Feed rate fluctuation causes extruded product dimension and quality fluctuation
Fenómeno do problema
Feed rate fluctuation causes extruded product dimension and quality fluctuation
Análise das causas
Unstable feeding screw speed, feed fluctuation
Raw material bridging in the hopper, material interruption
Gravimetric feeder calibration deviation
Feed rate not matched with extrusion speed
Uneven cellulose acetate butyrate particle size, unstable feeding
Solução
Stabilize feeding screw speed
Prevent hopper bridging (vibrating hopper)
Regularly calibrate the gravimetric feeder
Match feed rate with extrusion speed
Ensure uniform raw material particles
Conclusão principal
Feeding requires stable supply and bridging prevention
