High-Velocity Twin-Screw Extruder / Pelletizing Solution

Our twin-screw extruder is a high-velocity, co-rotating extruder perfect for your compounding requirements. Our robust extruders provide dependability in the most challenging tasks, such as the extrusion of plastics with high percentages of fillers, reinforcing fibers, or with heat-sensitive or shear-sensitive additives (such as flame retardants, glass fibers, etc.). You will find our twin-screw extruders to be highly advantageous in the production of rigid PVC and wood fiber blends.

Working Principle

All extruders from Rumtoo Recycling come standard with our patented Heat Wave Stabilization™, where heat is uniformly dispersed throughout the entire length of the barrel. This uniform distribution of heat, combined with co-rotating screw shafts that evenly blend the molten plastics into each other (in a figure 8 motion), creates the optimal environment for the plastic pelletizing process. We also manufacture counter-rotation extruders based on our customer’s needs and specifications.

Our extruders also come standard with a hydraulic screen changer to ensure uninterrupted operation during screen changes. Made of premium blended steel reinforced using gas nitriding technology, the drive shaft and barrel are specially treated to guard against corrosion and wear.

Taking the best of both worlds, a twin-screw extruder can be coupled with a single-screw extruder and a 2-stage array. In this setup, a larger twin-screw extruder is used mainly for the purpose of mixing and compound dispersion. The molten plastic from this process then travels to a smaller, single-screw extruder, where superior material extruding can be accomplished.

Depending on your preference for “melt pelletizing” or “strand pelletizing,” a water-ring cutter or pellets granulator with water tank can be added. To further enhance automation, a vertical dewatering machine with blower to a product silo can also be implemented. Rumtoo Recycling Machinery is your comprehensive solution to your pelletizing needs.
