Jet Mill vs Hammer Mill: Choosing the Right Mill for Your Powder

Choose a jet mill when you need particles below ~50 μm down to 1–30 μm with low heat and no cross-contamination; choose a hammer mill when you need coarse-to-medium cuts (25–200 μm) at the lowest cost per kilogram. The deciding inputs are target size, heat sensitivity and throughput.

Decision table

• Target ≤30 μm or heat-sensitive API: jet mill (spiral, 1–30 μm, 0.035–250 kg/h) — no heat build-up, closed dust-free milling.
• 25–200 μm at high throughput: hammer mill (10–2,500 kg/h across five models) — lowest cost per kg.
• D90 ≤5 μm crystalline, medium batches: pin mill (FSZ, 5–300 kg/h) — finer than hammer, cheaper than jet.

Scale-up matters

• Lab results must reproduce in production: mill chamber principle (not just label size) decides whether your lab distribution translates — test on the same chamber family before committing.

FAQ

Which mill gives 1–30 μm particle size?
A spiral jet mill (MC series) — 1–30 μm from 0.035 kg/h trials to 250 kg/h production, with no heat build-up and no moving parts in the mill chamber.
