TPE / TPV compounding

The VMI-AZ PLANETRUDER® is used as side feed extruders in continuous mixing applications for both thermoplastic elastomers (TPE / TPV), as well as rubber mixing. In such applications, the Planetruder® is connected to the compounding extruder feeding an extremely high precision continuous strip. In most continuous mixing applications a co-rotating twin screw is utilized (a practice well known in the plastic industry).

The Planetruder
®, as a side feeder for compounding extruders, offers the following advantages:
  • Due to the working principle of planetary gear pump the feeding precision of the Planetruder® is better than ± 0.4%.
  • Inside the Planetruder® the rubber is always pre-heated and enters the compounding extruder at a given temperature, which simplifies the compounding process compared to cold pellet feeding.
  • The compact design of our single drive Planetruder® can be simply attached to the compounding extruder without taking up excessive space.
  • The planetary gear pump system is 100% leakage free.
  • The Planetruder can handle strips. Rubber pelletizing is no longer required.
The following Planetruder ® extruder are availible:

  Type Output kg/h
  PLANETRUDER ® S 30 kg/h
  PLANETRUDER ® M 140 kg/h
  PLANETRUDER ® L 250 kg/h
  PLANETRUDER ® XL 500 kg/h
  PLANETRUDER ® 3XL 1600 kg/h

Note: the output is dependent on the compound
