Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch pelletizing, in particular to a masterbatch pelletizing machine. Background Art

[0002] Masterbatch refers to a plastic colorant made of a high proportion of pigments or additives and thermoplastic resins, which are well dispersed.

Masterbatch coloring is the most commonly used plastic coloring method today. The particle size of existing masterbatches is uneven when they are pelletized, which is not convenient for subsequent use. The masterbatches that do not meet the required particle size after pelletizing need to be screened and re-pelletized, which is inefficient. Based on this, a masterbatch pelletizer is designed.
