CEF screw slipping
Problembeschreibung
During CEF extrusion, the screw slips, the feeding does not advance, and the output drops sharply
Ursachenanalyse
The CEF particles melt too early in the feeding section, forming a lubricating film and causing the screw to slip; the feeding section temperature is too high
Lösung
1) Reduce the feeding section temperature by 10-15°C to delay melting; 2) Deepen the feeding section thread to increase the gripping force; 3) Dry the particle surface to reduce lubrication
Wichtigste Erkenntnis
Screw slipping is caused by premature melting; reducing the feeding section temperature is the key
