Benelabo’s powder processing line covers the full solid dosage front end: jet mills for 1–30 μm micronization from 0.035 to 250 kg/h, hammer and needle mills for deagglomeration and size reduction, a mobile granulator for charged sizing, a centrifugal sifter for fraction control, twin-screw feeders for consistent powder delivery, and the S-LAB multifunction lab mill for formulation work. One engineering team therefore sizes your entire powder train — feed, milling, classification — instead of leaving you to stitch together single-purpose machines. Selection is parameter-driven: target median particle size and distribution, throughput, heat sensitivity and flow behavior decide between jet and mechanical milling, and every recommendation can be verified on your own material through the sampling service before you commit to a production unit.
The Equipment Family
Machines and Where They Fit
| Machine | Size window | Best for | Page |
|---|---|---|---|
| Jet Mill MC series | 1–30 μm, 0.035–250 kg/h | Heat-sensitive APIs, narrow distributions, no thermal load | |
| Pin Mill (Needle Mill) | D90 to 5 μm class | Soft-to-medium crystalline powders, deagglomeration | |
| Hammer Mill | 25–200 μm to 2,500 kg/h | High-throughput sizing, brittle materials, granules | |
| Centrifugal Sifter | Gentle delumping | Post-dry delumping, consistent powder size | |
| Twin Screw Powder Feeder | Loss-in-weight dosing | Cohesive, fluffy or electrostatic powders that will not flow | |
| Mobile Granulator | Oversize reprocessing | Wet-mass sizing and rework at the bowl side |
Jet Mill or Hammer Mill?
The decision is driven by target size and thermal sensitivity: below roughly 50 μm, or whenever the API degrades with heat, the jet mill wins — energy comes from expanding air and particle-on-particle impact with no hot surfaces. Above 25 μm with a tougher, less sensitive material, the hammer mill delivers far higher throughput at lower air cost. The full decision table — including needle-mill duty between the two — is in our article Jet Mill vs Hammer Mill.
From Grams to 250 kg/h on One Principle
Every MC jet mill shares the same spiral-chamber principle, so a distribution developed on an MC-50 transfers to MC-400 by adjusting feed rate and air — not by re-developing the process. The S-LAB multifunction lab mill extends this to five powder processes on one bench, and particle size distribution is verified with a documented chart for every trial (what it takes to hit 1–30 μm).
