Core Advantages
Heat Wave Stabilization
Supports more uniform heat distribution for more consistent melt flow and pellet quality.
High-Precision Gearbox
Delivers quiet, steady power to the screw shaft for continuous, long-term operation.
Durable Construction
Barrel and screw are built from fortified, gas-nitrided steel for better resistance to wear and corrosion.
Smart Temperature Control
Centralized control helps maintain more stable processing temperatures automatically.
The Pelletizing Process
From raw material to finished pellets, the line streamlines each stage for efficiency and more stable output.
Feeding
Clean, dry plastic scrap is loaded into the hopper and fed into the barrel.
Melting and Conveying
The rotating screw melts and propels the plastic through the heated barrel.
Filtering and Degassing
Molten plastic passes through a screen changer and degassing zone to remove impurities.
Pelletizing
The clean melt is extruded through a die and cut into uniform pellets by the pelletizer.

Frequently Asked Questions
What is Heat Wave Stabilization?
It is Rumtoo's temperature-control concept for maintaining more uniform heat distribution across the barrel to improve melt consistency and reduce material degradation.
What pelletizing options are available?
You can choose between melt pelletizing with a water-ring cutter and strand pelletizing with a water tank, depending on your material and process target.
Can the pelletizing process be automated?
Yes. The line can be configured with dewatering and conveying equipment to move finished pellets to a product silo and support more automated operation.
What materials are the screw and barrel made of?
The barrel and screw shaft are made from high-strength steel with gas nitriding treatment for improved wear resistance and corrosion resistance.
What is the warranty on these machines?
Rumtoo recycling machines include a one-year limited warranty together with ongoing technical support and customization service.
