Controlled delumping and sizing
Conical Mill
Conical mill for pharmaceutical dry and wet granule sizing, delumping and controlled particle conditioning with screen and impeller selection.
Short Answer
A conical mill sizes powders or granules through a selected screen using a rotating impeller, making it useful for controlled delumping and OSD granule conditioning.
Process position
Where A Conical Mill Fits In The Process

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 conical mill is a screen-based size reduction machine used to delump powders and size wet or dry granules with controlled milling energy.
Working Principle
A rotating impeller pushes material across a conical screen. Product is reduced or sized as it passes through the screen openings and discharges to the next process step.
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 powders and excipients
- Wet granules before drying
- Dried granules after fluid bed drying
- Sensitive powders requiring gentler sizing
- API and nutraceutical materials after URS review
Target Particle Size / Control
Catalogue information lists screen openings from 0.5 mm to 10 mm and fine sizing capability around 150 micron depending on product. Final distribution should be confirmed by test or technical evaluation.
Capacity Range
Capacity depends on model and material. Catalogue data covers lab to production models, with throughput to be confirmed from density, moisture and target sizing.

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 wet product stickiness and cleaning access for wet granule applications.
- Confirm containment and dust extraction if the mill is used for API or fine powders.
- Select stainless steel contact parts and cleanable seals according to URS.
- Documentation support and FAT/SAT/IQ/OQ support are available if required.
Optional Configurations
- Top-drive or bottom-drive execution
- Interchangeable screen and impeller sets
- Mobile frame or integrated line mounting
- Vacuum conveying or gravity feed interface
- Controls and safety interlocks according to project scope
