Frequent screen clogging in EEA extrusion
Sorun Belirtisi
EEA extrusion requires screen replacement every 2-3h, clogging causing sudden pressure rise and output decline
Neden Analizi
Many gel particles and impurities in the raw material; screen mesh too high intercepting a large number of particles; filler or color masterbatch agglomerating and clogging the screen
Çözüm
1) Select raw material with low gel content; 2) Adopt stepped screens 40/80/120 mesh; 3) Add filler and color masterbatch by masterbatch method to reduce agglomeration; 4) Install an automatic screen changer to reduce downtime
Temel Çıkarım
Screen clogging is caused by impurities and improper configuration; raw material control and stepped screens are the key
