Unstable EEA extrusion feeding
Problembeschreibung
EEA extrusion feeding amount fluctuates ±15% causing unstable extrusion pressure and product dimensions
Ursachenanalyse
EEA granules irregular in shape causing unstable filling rate of the feeding screw; bridging or voids in the hopper; feeding screw design unsuitable
Lösung
1) Use gravimetric feeder to precisely control feeding amount; 2) Install a vibrator on the hopper to prevent bridging; 3) Granulate EEA to uniform particle size of 2-3mm; 4) Change the feeding screw to a special design
Wichtigste Erkenntnis
Unstable feeding is caused by granule characteristics; gravimetric feeding and anti-bridging are the core
