Granulation line with extruder is an automated production system that processes plastics, rubber, chemical raw materials and other materials into granular products through melting, extrusion, cutting and other processes. This line is widely used in industries such as plastic processing, chemical industry, food industry and pharmaceutical industry. Below is a detailed description of its main components and workflow.

I. Main components of the production line

1. Raw material supply system

   • Hopper/automatic loader: Feeds raw materials (such as powder, granules or recycled material) into the extruder, can be equipped with drying or preheating function.

   • Dosing device: Ensures precise mixing of raw materials with additives (such as dyes, stabilizers).

2. Extruder (main equipment)

   • Single screw/twin screw extruder:

     • Single screw: Suitable for common plastics (such as PE, PP), simple structure, low cost.

     • Twin screw: Suitable for high-fill and heat-sensitive materials (eg PVC, biodegradable plastics), ensures better mixing.

   • Heating and temperature control system: Zone heating (cylinder, die), precise control of melting temperature.

   • Replaceable filter element: Removes impurities in the melt, increasing product purity.

3. Die and pellet cutting system

   • Die design: The shape of the holes is selected depending on the required shape of the granules (cylindrical, hemispherical, etc.).

   • Cutting methods:

     • Hot cutting (underwater): The melt is cut immediately after leaving the die, suitable for viscous materials, provides a smooth surface of the granules.

     • Cold cutting (cutting harnesses): The melt is cooled to a solid state, then cut, suitable for hard plastics (eg ABS).

4. Cooling and drying system

   • Water bath/air cooling: Quickly cools granules to prevent sticking.

   • Centrifuge/vibrating sieve: Removes surface moisture, keeping granules dry.

5. Finishing equipment

   • Vibrating sieve: Separates quality granules from crumbs.

   • Packaging system: Automatic weighing and packaging (vacuum packaging possible).

6. Control system

   • Control via PLC or touch panel, integrated monitoring of temperature, rotation speed and pressure for production automation.
