🔍 Product Description
Twin Screw Extruder Overview

Clamshell Barrel Co-Rotating twin screw extruder for Master batch Compounding

  • Masterbatch is a concentrated mixture of pigments and/or additives encapsulated during a heat process into a carrier resin which is then cooled and cut into a granular shape.
  • The co-rotating twin screw extruder will melt, mix, and knead the dry blend of resin carrier and pigments and additives, pelletizing them into perfect master batch pellets by water strand pelletizing.
  • The clamshell barrel co-rotating twin screw extruder can be opened for cleaning, checking, and maintenance. It is ideal for color changing for Master batch compounding.

Clamshell Barrel Co-rotating Twin Screw Extruder for Master batch

The barrel can be opened in minutes. This makes product changeover, maintenance and research fast and easy. Both screws and barrels are designed using the building block principle. The screw configuration, barrel setup, feeding and venting, screen changing, way of pelletizing and process requirements are all optimized for the machine's versatility in general applications.

❓ Frequently Asked Questions
What are the advantages of a Clamshell Barrel?
The clamshell barrel can be opened in minutes, which allows for extremely fast cleaning, visual inspection of the processing state, and easy maintenance. This is particularly beneficial for production lines with frequent color or material changes.
What materials are suitable for the PSHJ series extruders?
These machines are designed for all kinds of polymer mixing, especially for masterbatch compounding where concentrated pigments and additives are mixed into carrier resins.
Can I use this machine for laboratory research?
Yes, the PSHJ-20 model is an ideal lab-scale compounding machine. It allows you to freely build up screw geometries and check mixing status, making it perfect for SPC masterbatch R&D.
What is the production capacity range of these extruders?
The capacity depends on the model. It ranges from 2-15 kg/hr for the lab-scale model (PSHJ-20) up to 800-1500 kg/hr for the large industrial model (PSHJ-127).
What kind of control system do the machines use?
The machines are equipped with an automatic control system featuring a PLC and a Touch Screen interface for easy operation and precise parameter management.
What electrical components are used in the extruder?
We use high-quality international brands for electrical components, specifically Siemens and Schneider, to ensure reliability and global compatibility.
