Co-Rotating Parallel Twin-Screw Extruder

Product Features:

The core feature of the co-rotating twin-screw extruder is its mixing and dispersing capability.The modular"building-block"design of the screws and barrels allows users to freely combine conveying,mixing,shearing,and venting elements based on the formulation and process,enabling customization.The high-speed screw design provides a broad processing window,while the intermeshing threads'"self-cleaning"function prevents material stagnation and degradation,ensuring product purity and batch consistency.Equipped with multiple feed ports and a powerful vacuum venting system,it can simultaneously incorporate various components(e.g.,base polymer,fillers,additives)and effectively remove volatiles.The machine features a high-torque design and robust construction for harsh process conditions.

Product Specifications:

This machine has a screw diameter of 52mm with a parallel design and a centerline distance of 52mm.The high L/D ratio of 40:1 or more provides ample length for complex mixing and venting processes.The main drive is a high-power(110kW)motor,delivering high torque for stable operation at high speeds.The barrel is modular,typically consisting of 8-10 sections,including main and side feed ports and at least two vacuum vent ports.The heating/cooling system often uses electric heaters combined with circulating water cooling for precise temperature control.The control system integrates an advanced PLC and industrial computer,capable of storing numerous recipes and monitoring key parameters like torque,pressure,and temperature in real-time,which is essential for precision compounding.

Product Applications:

This equipment is primarily used in the high value-added field of plastic modification.It is the core equipment for producing various color masterbatches and additive masterbatches(e.g.,flame retardant,antioxidant).In engineering plastic modification,it is used to prepare glass-fiber reinforced,mineral-filled,and toughened materials like Nylon(PA),Polycarbonate(PC),and Polyester(PBT/PET).It is also used for producing specialty polymer materials such as biodegradable plastics,conductive plastics,and wood-plastic composites.Furthermore,in reactive extrusion,it can be used for polymerization,grafting,or controlled degradation of polymers.It is essential equipment for research institutions and high-performance plastic manufacturers.
