This ensures that the recycled granules have consistent properties and good processability.
Low Specific Power Consumption: Despite their high performance, twin-screw extruders have low specific power consumption (power consumption per unit output), making them more energy-efficient compared to single-screw extruders for certain applications. This helps to reduce operating costs for recycling enterprises.
High Volume Power: Twin-screw extruders have a high volume power (power per unit volume of the barrel), which means they can process a large amount of material in a small space. This makes them suitable for large-scale production operations with limited space.
