Milling method comparison
Cone Mill vs Hammer Mill
Compare cone mills and hammer mills for pharmaceutical powder delumping, granule sizing, particle size reduction and process integration.
Short Answer
Cone mills are often used for controlled delumping and granule sizing, while hammer mills are used for more aggressive size reduction. Selection depends on target particle size, heat sensitivity, containment and cleaning needs.
Practical explanation
How To Think About This Decision
Use the guide as an engineering checklist before preparing a URS, layout review or quotation request.
A cone mill uses a screen and impeller to condition powders or granules with controlled residence time. It is common in OSD processes before blending or after drying.
A hammer mill uses impact for stronger particle size reduction. It can be suitable when a finer target is needed, but heat generation, dust and cleaning should be reviewed.
For pharmaceutical projects, the milling method should be selected after reviewing feed material, target distribution, capacity, containment and downstream process risk.

Quotation input
What Information Is Needed For Quotation
A clear inquiry lets the engineering team review process step, powder behavior, capacity, containment level and layout constraints before proposing an equipment scope.
Powder name, bulk density, particle size range, flowability and moisture sensitivity.
Required batch size or hourly capacity, transfer distance, elevation and number of bends.
Target process step, upstream equipment, downstream equipment and room layout constraints.
Containment, dust extraction, cleanroom, cleaning and material contact expectations.
Preferred automation level, documentation support and FAT/SAT/IQ/OQ support needs if required.

FAQ
Frequently Asked Questions
Which mill is gentler?+
A cone mill is generally selected for gentler delumping and sizing, but the final choice depends on screen, speed, impeller and product behavior.
Can a cone mill be used after drying?+
Yes. Cone mills are commonly used for dried granule sizing after fluid bed drying.
What data is needed for mill selection?+
Feed particle size, target size, capacity, heat sensitivity, moisture, density, containment level and cleaning expectations are important.
