Product Overview

The Masterbatch Twin Screw Granulator is a co-rotating twin screw extrusion system designed for industrial compounding of color masterbatch, CaCO₃ filler masterbatch, and functional additive masterbatch.

It is suitable for continuous production processes that require stable mixing, uniform dispersion, and consistent pellet quality. Compared with conventional single screw extrusion systems, the co-rotating twin screw design offers higher mixing efficiency, greater formulation flexibility, and more stable processing performance for com.

Applications

The Masterbatch Twin Screw Granul

Color masterbatch
Black an
Calcium carbonate (CaCO₃) filler
Functional additive masterbatch
Engineer
Plastic modification
Recycled plastic compounding

Working Principle

Raw materials are continuously fed into the twin screw extruder through the feeding system. Inside the barrel, the co-rotating screws transport, melt, mix, shear, and disperse the materials under precisely controlled temperature conditions.

After complete homogenization, the molten material passes through a filtration system before being extruded into strands or directly.
