Impact milling equipment
Hammer Mill
Hammer mill for pharmaceutical powder milling, pulverization and size reduction of dry, crystalline or fibrous materials with model selection based on material testing.
Short Answer
A hammer mill uses high speed impact to reduce dry powders and brittle materials for pharmaceutical, API, nutraceutical and fine chemical processing.
Process position
Where A Hammer Mill Fits In The Process
The hammer mill is typically positioned after material charging or pre-breaking and before sieving, blending, granulation feed or final downstream transfer.

Product data
What It Is And How It Works
Use this product data as a starting point for equipment selection. Final configuration should be confirmed against URS, material characteristics and testing where required.
What It Is
A hammer mill is an impact size reduction machine used for dry powder milling, pulverization and particle conditioning where stronger milling energy is required.
Working Principle
Material enters the milling chamber and is impacted by a high speed rotor. Particles are reduced by impact and pass through a selected screen before discharge to sifting, transfer or collection equipment.
Material and sizing
Suitable Materials, Particle Size And Capacity
Particle size and throughput are process results, not generic promises. They depend on material behavior, selected model and operating parameters.
Suitable Materials
- Dry pharmaceutical powders
- Crystalline API or excipient materials
- Brittle or fibrous powders
- Nutraceutical powder ingredients
- Fine chemical powders after material compatibility review
Target Particle Size / Control
Particle size is mainly controlled by screen opening, rotor speed, feed rate and material behavior. Catalogue information indicates fine milling capability and screen openings from 0.15 mm to 10 mm; actual particle size should be confirmed by test.
Capacity Range
Capacity depends on model and material. Catalogue data covers lab, pilot and production models, with final throughput to be confirmed by technical evaluation.

Pharmaceutical Considerations And Optional Configurations
Selection should consider cleanability, containment, documentation expectations, utility conditions and the way the machine connects to upstream and downstream process steps.
Pharmaceutical Considerations
- Review heat generation when processing temperature-sensitive API or excipients.
- Confirm dust control and containment when milling fine or potent powders.
- Select cleanable contact parts and seals according to URS expectations.
- Documentation support and FAT/SAT/IQ/OQ support are available if required.
Optional Configurations
- Interchangeable screens
- Vacuum conveying feed or discharge
- Dust extraction connection
- Mobile or fixed installation
- PLC/HMI controls depending on project scope

FAQ
Frequently Asked Questions
When should a hammer mill be selected instead of a cone mill?+
A hammer mill is usually considered when stronger impact milling or finer reduction is needed. A cone mill is often preferred for gentler delumping or granule sizing.
Can final particle size be guaranteed without testing?+
No. Target particle size depends on material properties, screen selection, speed, feed rate and heat sensitivity, so testing or technical evaluation is recommended.
What capacity range is available?+
Capacity depends on model and material. Supplier catalogue data includes lab through production models, and final throughput should be confirmed after material review.
