Study on the melting performance of single screw extruder with grooved melting zone and barr screw

- A melting mechanism for SSE with grooved melting zone (GMZ) was established.
- Experiments on a new SSE platform with hydraulic-clamshell type barrels.
- The melting efficiency was improved by introducing GMZ to SSE.
- Heat convection and viscous dissipation are main melting heat for SEE with GMZ.
