What are the main production processes of PVC cable materials?
Due to different production equipment, what are the main production processes of PVC cable materials?

There are mainly the following four ways:

1. Granulation by double-roll mill: raw materials → batching → high-speed mixer → internal mixer → double-roll mill → cooling water tank → drying → granulator → screening and magnetic separation → metering → packaging.

2. Granulation by single screw extruder: raw materials → batching → high-speed mixer → cooling mixer → single screw extruder → hot cutting head → air cooling → screening and magnetic separation → metering → packaging.

3. Granulation by two-stage extruder (first-stage twin-screw extruder and second-stage single-screw extruder): raw materials → batching → high-speed mixer → cooling mixer → second-stage extruder → hot cutting head → air cooling → screening and magnetic separation → metering → packaging.

4. Granulation by twin-screw extruder: raw materials → batching → high-speed mixer → cooling mixer → twin-screw extruder → hot cutting head → air cooling → screening and magnetic separation → metering → packaging.
