How Each Pelletizer Works

Strand Pelletizer Process

Ho pholisa le ho Seha

Strand pelletizer systems operate by transforming molten polymer into cylindrical pellets. The process begins with feeding material into the compactor using a belt conveyor. The feeding speed can be adjusted, and metal detection is often included to prevent contamination. Rotary blades inside the compactor shred and heat the material, densifying it before it enters the extruder screw. The extruder melts the polymer, and a vacuum system removes impurities. Once the polymer is fully melted, it moves to the die head. Here, the molten strands are cut and cooled in a water ring, which eliminates the need for manual strand handling. The water ring ensures rapid cooling and helps maintain pellet shape.

Hlokomela: The water ring cooling method in strand pelletizer systems is efficient for most engineering plastics, but may struggle with sticky or low-viscosity polymers.
