Loading
Sanitary conical sizing mill for wet lump reduction and dry granule de-agglomeration with low-heat generation and narrow particle size distribution.
Up to 1,500 kg/hour throughput
The CM-250 Conical Sizing Mill uses a rotating impeller inside a conical screen to gently size wet granulated mass or dry compacted flakes. With tip speeds up to 40 m/s, the CM-250 achieves high throughput with up to 50% fewer fines compared to traditional hammer mills.

* Specifications may vary by model. Contact us for exact configuration.
Third-party certification of the quality management system under which every machine in the range is designed, built and tested. It certifies the process, not the performance of an individual machine.
Evidence: ISO 9001:2015 Quality Management System Certificate (PDF · 2 KB)World Health Organization guidance on good manufacturing practice, widely used as the reference for export markets and WHO prequalification.
United States current Good Manufacturing Practice regulation for finished pharmaceuticals, including equipment design, cleaning and maintenance requirements (21 CFR 211.63 and 211.67).
All configurations
Confirms that the CM-250 design, as specified, meets the user requirement specification before manufacture begins.
GMP configurations
Documents that the machine is installed to drawing, connected to the specified utilities and calibrated.
GMP configurations
Challenges the machine across its operating ranges, alarms and interlocks to show it performs as specified.
Customer-executed; product-specific acceptance criteria
Executed by the customer with our support: three consecutive batches with granule size distribution, loss on drying and blend uniformity within limits.
All configurations; customer witnessing optional
Witnessed at our works before dispatch, so defects are corrected where the parts, tools and engineers are.
All configurations
Repeats the critical FAT checks at the customer site after installation and utility connection.
