CEF extrusion screen frequent clogging
Problembeschreibung
The CEF extrusion screen needs to be replaced every 2-3h, clogging causes a sudden pressure rise and a decrease in output
Ursachenanalyse
There are many gel particles and impurities in the raw material; the screen mesh is too high and intercepts a large number of particles; fillers or color masterbatch agglomerate and clog the screen
Lösung
1) Select raw materials with low gel content; 2) Adopt stepped screens 40/80/120 mesh; 3) Add fillers and color masterbatch by the masterbatch method to reduce agglomeration; 4) Install an automatic screen changer to reduce downtime
Wichtigste Erkenntnis
Screen clogging is caused by impurities and improper configuration; raw material control and stepped screens are the key
