Plastic recycling granulator are that the exhaust hole is blocked, the vacuum degree changes or the volatile matter in the raw material changes. Possible ways to improve exhaust efficiency can refer to the following methods:

1. Increase barrel temperature in the first stage;

2. Increase the vacuum degree in the exhaust hole;

3. Preheating raw materials;

4. Use stripping agent.

The plastic recycling granulator can also greatly affect the exhaust efficiency, and the exhaust section of the multi-thread can improve the exhaust. In addition, it is very important that the polymer is completely melted in the first stage of the screw, and having a trough mixing section at the end of the first stage of the screw will help ensure complete melting.
