What is a Cone Mill?
A Cone Mill, also known as a Conical Mill or Co-Mill, is a low-energy particle size reduction system that uses a rotating impeller inside a conical screen chamber to gently process powders, granules, agglomerates, and dry bulk materials.
Unlike high-impact grinding systems, Cone Mills are designed for:
- Gentle size reduction
- Deagglomeration
- Granule sizing
- Product conditioning
- Uniform particle distribution
- Low heat processing
Cone Mills are ideal for products that require minimal degradation and careful particle handling.
How Cone Mills Work
DP® Cone Mills utilize a rotating impeller positioned inside a conical screen chamber.
The process works as follows:
- Product enters the conical milling chamber
- The impeller rotates at controlled speed
- Material is gently forced against the screen surface
- Particles are reduced and conditioned as they pass through the screen openings
- Finished product exits the system with controlled particle size distribution
Particle size can be controlled through:
- Impeller speed
- Screen size
- Screen geometry
- Feed rate
- Impeller design
The gentle milling action minimizes:
- Heat generation
- Product degradation
- Dust formation
- Excessive fines
