PET recycled bottle flakes agglomerate after drying
Sorun Belirtisi
PET recycled bottle flakes agglomerate and bridge in the drying hopper and cannot feed normally.
Neden Analizi
Drying temperature is too high (>170°C); bottle flake surfaces soften and stick together; time is too long; low-melting-point PVC label residues are mixed in.
Çözüm
Control drying temperature ≤165°C; control material level ≤70%; add a stirring device to prevent bridging; strengthen sorting to remove PVC.
Temel Çıkarım
Agglomeration of PET bottle flakes during drying is a common problem in recycling processing.
