The VSG series spans 14 high-shear wet granulator specifications from 0.5 L to 800 L — servo-driven impeller with live torque curves, four quick-change bowls and automatic binder dosing at ≤65 dB.
Highlights
Servo impeller drive plots the torque curve live — granulation endpoint is a number, not a feel.
Swap bowl sizes on one base to cover R&D through production batches.
Peristaltic pump dosing with Watson-Marlow-class accuracy.
Applications
- Wet granulation for tableting
- RS/SG ray-granulation
- HPMC/povidone binder systems

FAQ
What size wet granulator do I need for 10 kg batches?
At typical 0.4 bulk density, a 10 kg batch needs ~25 L working volume — VSG-50 (30–80 L working) gives headroom; VSG-30 (9–24 L) suits dense formulations. Final sizing uses your formula’s bulk density.
How does torque monitoring improve granulation endpoint control?
Wet mass consistency shows up as impeller torque. The servo system displays the live torque curve, so granulation endpoints (growth plateau, over-wetting onset) are read from data instead of operator feel — and the curve becomes your scale-up record.
Can the granulator switch bowls for different batch sizes?
Yes — four bowl volumes are quick-change on the same base, letting one machine serve multiple batch sizes on one line.
