I. Core Configuration: Setting the Industry Standard for Performance
The KTE-50A extruder features a proven design, with key components sourced from leading industry brands to meet diverse production needs.
The main unit is designed with a 40:1 length-to-diameter ratio, paired with a 45kW Wannan main motor and Delta variable-frequency drive. This configuration delivers stable, high torque output, enabling the machine to easily handle complex applications such as high-filler and glass-fiber-reinforced materials. The barrel and screw are constructed from wear- and corrosion-resistant alloy materials, significantly extending equipment lifespan and reducing maintenance costs. The temperature control system, equipped with Omron temperature controllers and VMI pressure gauges, enables precise multi-zone temperature regulation to ensure uniform material plasticization. The hydraulic plate-type screen changer supports rapid screen changes to minimize downtime, efficiently filters impurities from the melt, and guarantees the purity of the finished product.

II. Comprehensive System Integration: Building a Fully Automated Pelletizing Production Line
The equipment is equipped with a complete auxiliary system, enabling fully automated production from raw material feeding to finished pellets:
Precise Feeding System: Equipped with loss-in-weight batching and side-feed devices, it supports simultaneous metering of multi-component materials, offers high feeding accuracy, and accommodates complex formulation production.
Cooling and Drying Unit: A stainless steel cooling water tank paired with a blow dryer enables rapid cooling and shaping of the extruded strands, followed by vibrating screen classification to ensure pellet uniformity.
Pelletizing and Conveying System: A variable-frequency-controlled gantry pelletizer paired with a screw feeder enables automated integration, reduces manual intervention, and enhances production efficiency.

III. Wide Range of Applications, Suitable for Material Processing Across Multiple FieldsWith excellent mixing performance and flexible process configurations, the equipment meets production needs across various scenarios:
Plastic Modification: Granulation of glass-fiber-reinforced, mineral-filled, and flame-retardant modified plastics
Functional Masterbatches: Efficient compounding and granulation of color masterbatches, functional masterbatches, and filler masterbatches
Polymer Materials: Granulation of plastic alloys, biodegradable materials, and modified recycled plastics
Specialty Materials: Stable processing of high-viscosity and highly filled materials

This high-performance twin-screw extruder incorporates an industry-leading modular design concept, with all key components technically optimized to balance performance and durability:
High-Torque Gearbox: Equipped with an 11.5 torque-class gearbox (specific torque of 11.5 Nm/cm³), it is suitable for high-power, high-output, and highly-filled material production lines. It offers high transmission efficiency, low operating noise, and significantly extended equipment lifespan, meeting the demands of long-term continuous production.
Customizable Barrel System: The barrel features a segmented modular design with built-in spiral water cooling channels and electric heating elements. Each segment is independently temperature-controlled, achieving a temperature accuracy of ±1°C. Barrel materials can be selected based on material properties, including 38CrMoAl, 45# high-chromium alloy, or WC-Co powder alloy liners, making it suitable for processing highly filled and highly abrasive materials.
High-wear-resistant screw elements: The core twin-screw elements feature a modular combination structure that can be freely configured to meet various process requirements, enabling material conveying, melting, shearing, mixing, degassing, and pressure-building extrusion. Elements are available in wear- and corrosion-resistant materials such as CPM-10V and SKD11, effectively extending equipment service life and reducing maintenance costs.
High-efficiency drive system: Equipped with high-efficiency, low-noise AC variable-frequency or permanent magnet synchronous motors, the system offers smooth operation and strong overload capacity. Customized configurations can be provided based on the customer’s on-site environmental requirements to achieve an optimal balance between performance and cost.
