Basket extruder for large-volume pellet manufacturing

Vertical Pelletizing Extruder (Production-Scale)

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.

Specifications

Features

1.Continuous and efficient operation

Supports uninterrupted feeding, extrusion, and shaping within an integrated process, ensuring high throughput and stable production.

2.Uniform extrusion with high yield

Maintains consistent pressure distribution for even density across extrudates, achieving a finished product rate of ≥99% and minimizing waste.

3.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.

4.Safe and stable performance

Equipped with overload protection and low-noise operation (<45 dB), ensuring operational safety and a comfortable working environment.

5.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
