JWB Extrusion-Rounding Coating Machine

Working Principle
Powdered or wet-mixed materials are fed into the extrusion module, forming continuous strands that are cut and conveyed to the centrifugal rounding section. Here, rotation and centrifugal force transform the extruded strands into uniform spherical pellets. The pellets then pass through a drying chamber where temperature and airflow are precisely controlled to remove excess moisture without degrading heat-sensitive materials. For coating operations, a controlled spray system evenly applies the coating solution while an integrated heating system maintains optimal conditions. Airflow and moisture supplementation systems ensure consistent pellet formation, and the combined process of extrusion, rounding, drying, and coating is automated to deliver high reproducibility and uniformity.

Key Features
Combines extrusion, pellet rounding, drying, and coating in a single laboratory-scale machine.

Precise temperature control protects heat-sensitive materials during drying and coating.

Capable of producing fine granules (0.1–0.3 mm) and micro-pellets larger than 0.3 mm.

Centrifugal rounding ensures high repeatability and excellent pellet sphericity.

Integrated airflow and moisture spray system adapts to different product requirements.

Automated coating system with precise spray control and temperature regulation for uniform coverage.

Designed in compliance with cGMP standards for easy cleaning, thorough sanitation, and minimal cross-contamination.
