Long tails/tailing on blend extrusion granulation particles
Problem Phenomenon
The cut particles have tails or are stringy
Cause Analysis
The pelletizer blade is worn or the blade gap is improper; melt temperature is too high, causing stringing during pelletizing; pelletizing speed does not match extrusion output speed
Solution
Replace with new blades and adjust the blade gap to a reasonable range; appropriately reduce melt temperature; synchronously adjust the pelletizing speed
Key Takeaway
Tailed particles affect the smoothness of subsequent feeding and metering accuracy
