Na gaba, you dry the pellets and get them ready for packaging. These systems help you make better pellets, work faster, and handle many types of plastics. The table below explains why factories like underwater pelletizing systems:

Factories can count on underwater pelletizing systems to work well every time.

FAQ

What plastics can you use in an underwater pelletizer?

You can use many nau'ikan robobi, kamar PE, PP, PET, PVC, da ABS. Most thermoplastics work well in these systems. Always check your material’s melting point and flow properties before starting.

Yadda za ku kiyaye pellets daga manne tare?

You keep pellets from sticking by cutting and cooling them underwater. The water cools the pellets quickly. This step helps each pellet keep its shape and stay separate.

Why is drying pellets important?

Drying removes water from the pellet surface. If you skip drying, pellets may clump or cause problems in later steps. Dry pellets store and handle better.

How often should you check the knife assembly?

You should check the knife assembly every shift or after a set number of hours. Dull knives make uneven pellets. Regular checks help you keep pellet quality high.
