Benelabo top spray guns cover 10+ models across fluid beds from 1 L lab bowls to 300 L+ production processors, with φ0.6–1.2 mm nozzle bores and two-fluid or three-fluid atomization — engineered so the gun set installs without changing your machine’s mechanical structure or control program.
Highlights
Two/three-fluid heads with CFD-optimized air caps narrow the droplet spectrum for consistent granule color and size.
Anti-deposition tip geometry plus quick-detach nozzles move cleaning from mid-batch downtime to between-batch routine.
Built to your machine’s mounting and connections — equivalent atomization, shorter lead time, lower lifetime cost.
Five/seven/eight-head assemblies serve large multi-nozzle beds from one lance.
Applications
- Fluid bed top-spray granulation and drying
- Retrofit upgrades of existing fluid beds
- Lab and pilot pellet lines
- Heated variants for hot melt duty

FAQ
How to solve fluid bed spray gun clogging?
Anti-clogging tip geometry, quick-detach nozzles and optional CIP cleaning balls; bore size is matched to your binder solids to stop blockage at the source.
Can I upgrade my fluid bed spray system without replacing the machine?
Yes — gun sets are built to your mounting and liquid/air interfaces; the main machine structure and control program stay untouched.
Which nozzle size should I choose?
φ0.6–1.2 mm standard: finer atomization and thin liquids smaller, high-solid binders larger. Share your fluid for a sized recommendation.
