• Mpekere na-atụgharị na-egbutu eriri ndị ahụ n'ime pellets.

• Water cools the pellets right away so they do not stick.

You must keep the process steady to get even pellets. The cutting uses high shear rates. The knife edge pushes into the polymer and adds stress. When the stress is high enough, the strand breaks cleanly. This makes smooth and round pellets. This process works for many kinds of plastics.

Die Plate Function in Pelletizing

The die plate is very important in pelletizing. It shapes melted plastics and controls pellet size. You must keep the die plate at the right temperature. If it is too cool, pellets may not form well. If it is too hot, pellets can stick or lose shape. The die plate also keeps the process stable and makes pellets uniform.

Ndụmọdụ: Use heaters built into the die plate to keep the best temperature for your plastics.

The table below shows how the water chamber works in the underwater pelletizing process:

You need to control the water temperature and flow rate for the best cooling. Most underwater pelletizing systems keep the water between 20°C and 40°C. This range works for many types of plastics. If you use semicrystalline polymers, you may need to adjust the cooling rate to get the right crystal structure.

You set up the water system before you start the pelletizing process. You make sure the water pump and filters work well. You also check the water stays clear and at the right temperature. Operators watch the system during production to keep everything running smoothly. The water depth in the chamber helps control how fast the pellets move. If the water is too shallow, pellets may not cool enough. If it is too deep, they may stay in the water too long and get too cold.

• The water carries the pellets to the dewatering and drying stages.

• You monitor the water flow to make sure pellets move at the right speed.

• Regular checks on the pump and filters keep the water clean and the process efficient.
