Counter-Rotating Plastic Processing Screw Design

The patent inverts the conventional approach by rotating the mixing and comminution implements in the opposite direction to the conveyor movement. This creates a counter-rotating effect that reduces feed pressure and prevents overfilling of the screw, allowing the screw to operate at lower rotation rates while maintaining productivity. The reverse rotation of mixing implements reduces mechanical and thermal stress on the plastic material, preventing molecular chain damage.

The patent applies reverse rotation of the mixing and comminution implements to reduce feed pressure and prevent overfilling of the screw. This allows the screw to operate with appropriate flight depth for material homogeneity while maintaining higher rotation rates and productivity. The counter-rotating mixing implements ensure uniform material distribution without requiring excessive flight depth.

The patent uses counter-rotating mixing and comminution implements to enhance material homogeneity through improved mixing action. This allows for shorter residence times in the container while still achieving the required thermal and mechanical homogeneity, thereby increasing overall productivity. The reverse rotation creates more effective mixing patterns that reduce the time needed for homogeneous material preparation.

The patent employs counter-rotating mixing and comminution implements to achieve effective material homogenization without requiring large container diameters. The reverse rotation creates improved mixing patterns and heat distribution, allowing for compact container designs that maintain manufacturing precision while reducing device complexity and space requirements.
