Type 75 twin-screw extruder for nylon plus fiberglass pelletizing

This production line is sent to Vietnam, the power of the main motor is 132 kilowatts, high efficiency and energy saving, high output, the customer specified the formula, in addition, we also help it to purchase the fiberglass, very much trust us.

Objectives

• Improve Production Efficiency: Increase output rates and reduce cycle times.
• Enhance Product Quality: Achieve consistent pellet size and uniform dispersion of fiberglass.
• Flexibility: Allow for quick changeovers between different formulations.

Equipment Overview

Type 75 Twin-Screw Extruder

• Screw Diameter: 71.5mm
• L/D Ratio: 44：1 (Length to Diameter)
• Motor Power: 132 kW
• Max Screw Speed: 600 RPM
• Output Capacity: 500-1000 kg/h

Key Features

• Modular Screw Configuration: Allows for customization based on the material and process requirements.
• High Torque Capacity: Ensures efficient mixing and compounding of nylon with fiberglass.
• Advanced Temperature Control: Precise heating zones ensure optimal processing temperatures.

Process Description

1. Material Feeding:

   • Nylon Resin and Fiberglass: Fed into the extruder through a gravimetric feeder system to ensure precise ratio control.

2. Compounding:

   • Twin-Screw Action: Provides thorough mixing and compounding of the nylon and fiberglass, ensuring uniform dispersion of fibers.

3. Melt Homogenization:

   • Temperature Management: The extruder’s advanced temperature control maintains the ideal melt temperature for nylon, preventing degradation.

4. Pelletizing:

   • Strand Pelletizing System: Extruded strands are cooled and cut into uniform pellets, suitable for further processing.

Results

• Increased Efficiency: Production output increased by 30%, reducing operational costs.
• Improved Product Quality: Consistent pellet size and superior fiber dispersion resulted in enhanced mechanical properties of the final product.
• Reduced Downtime: The modular design of the extruder allowed for rapid changeovers, minimizing downtime between production runs.
