Material leakage from the extruder
Thread Content
During operation, due to certain improper operations, extruders may experience material leakage at their feed inlet or other discharge ports. Has anyone conducted a systematic study on the factors that cause such leakage in extruders? I welcome any guidance or discussions on this topic
What type of extruder is it? The process structure of extruders varies across different industries and production stages
From our industry analysis: unstable materials； The distance between the plate and the reamer is not appropriate ； Another spiral, with its own solutions for each situation
The reasons are as follows: The solid content of the material entering the extruder is unstable, which leads to instability in the internal volatile content. As a result, the volume of the volatile gas varies, causing pressure instability. Gas obstruction occurs inside the barrel, and the gas phase cannot be discharged, preventing the material from being carried out through the devolatilization port
