SPJ Series Co-Rotating Twin Screw Extruder

SPJ Series Co-Rotating Twin Screw Extruder

The SPJ series co-rotating twin screw extruders are proven for the efficient, reliable and economic mixing, devolatilization and direct extrusion of wood and natural fiber plastic composites, such as phenolic molding plastic, epoxy electric sealing material, powder coating and other thermosetting resin ingredients. This twin screw extrusion equipment finds a wide variety of applications especially in the master batch, rubber and plastic compounding, plastic modification, fiber glass reinforcement, cable compound, toner, and so on. Co-rotating twin screw extruders usually have modular configurations and are thus quite flexible for adapting to changing tasks and material properties. Lantai has made significant contributions to the progress of co-rotating twin screw extrusion equipment design. We have introduced innovative technology which has further advanced twin screw extruder performance. It is the world’s leading technology and an initiative domestically.  For eight consecutive years, we have successfully finished tons of production.

Features of SPJ Series Co-Rotating Twin Screw Extruder:
1. This twin screw extrusion equipment adopts new designed gearbox and transmission system with high torque. The screw is in modular design and exchangeable.
2.  High precision gears, imported bearings and forced lubricating units guarantee high performance and reliable running.
3.  Co-rotating twin-screw extruder possesses multiform feeder systems for specialized process.
4.  This type of twin screw extrusion equipment is easy arranged.
5.  According to different materials, the material of barrel and screw elements will be different.
6.  Segmented barrel and screw construction provide longer service life and reduce life-cycle cost.
