What is a Twin-Screw Extruder?

Technical Description

A twin-screw extruder has two intermeshing screws rotating inside a barrel. The screws can be co-rotating (both rotate in the same direction) or counter-rotating. The design enhances mixing, heat transfer, and pressure generation. High-Torque Twin-Screw Extrusion Lines High-torque refers to the ability of the extruder to exert very strong rotational force on the screws. This enables processing of highly viscous, filled, or reinforced materials which need more mechanical energy to melt and mix. Often used for compounding plastics with additives, fillers, or fibers. Key Features: Robust Drive System: Motors and gearboxes designed to deliver high torque at relatively low screw speeds. Intermeshing Screws: Provide efficient mixing and shearing. Modular Screw Design: Screw elements can be customized for different processing needs. Advanced Controls: For temperature, speed, and pressure to ensure consistent quality. Versatile: Can handle a wide range of materials including thermoplastics, elastomers, and reactive systems. Applications: Polymer compounding and masterbatch production Recycling of plastics Production of food, pharmaceuticals, or chemicals requiring intensive mixing Processing filled or fiber-reinforced composites Advantages: Superior mixing and homogenization Ability to handle difficult or abrasive materials Enhanced process control and product quality Increased throughput due to higher torque capacity
