Vertical Pelletizing Extruder (Production-Scale)
Basket extruder for large-volume pellet manufacturing
The production-scale vertical pelletizing extruder is designed for large-volume manufacturing of uniform cylindrical pellets. It processes blended mixtures of powders, excipients, and wet binders into dense, consistent extrudates through a rotary extrusion mechanism. The material is evenly fed into the extrusion chamber by a rotating shaft feeder and compressed through the die plate to achieve smooth and continuous extrusion.

Features
- Continuous and efficient operation
Supports uninterrupted feeding, extrusion, and shaping within an integrated process, ensuring high throughput and stable production. - Uniform extrusion with high yield
Maintains consistent pressure distribution for even density across extrudates, achieving a finished product rate of ≥99% and minimizing waste. - Low-temperature, friction-free extrusion
Employs a rotary extrusion mechanism that prevents heat generation during processing, ideal for heat-sensitive materials such as pharmaceuticals or biological formulations. Compared with twin-screw extruders, it requires no external cooling, reduces energy use, and eliminates die plate cracking risks, simplifying maintenance and operation. - Safe and stable performance
Equipped with overload protection and low-noise operation (<45 dB), ensuring operational safety and a comfortable working environment. - Flexible die configuration
Offers multiple die plate sizes (Ø0.4mm-3.0mm), capable of producing uniform cylindrical extrudates from 0.5mm to 3.0mm, meeting diverse production-scale requirements.
Typical Applications
Extrusion performance of soft materials blended from herbal extract powder and excipients such as microcrystalline cellulose and lactose
Compatible Equipment
This extruder is typically paired with a spheronizer to form a complete pelletizing system.
