Two Screw Compounding Pellet Extruder for Calcium Carbonate Masterbatch - 5-1500kg/h Output with 28-60:1 L/D Ratio

The Two Screw Compounding Pellet Extruder is a specialized industrial system designed for calcium carbonate masterbatch pelletizing and various polymer compounding applications. This co-rotating twin screw extruder efficiently melts, mixes, and kneads dry blends of resin carriers with pigments and additives, producing high-quality masterbatch pellets through water strand pelletizing.

• Clamshell barrel design for easy cleaning, inspection, and maintenance
• Ideal for color changing in masterbatch compounding operations
• Multiple models available with output capacities from 5kg/h to 1500kg/h
• L/D ratios from 28:1 to 60:1 for optimal processing flexibility
