The SDx Series

Pilot-scale & mid-size milling platform

Effective, reliable, and efficient powder milling technology with scalable results.


Milling & screening platform for mid-sized capacities

Presenting the next phase of our cutting-edge product development in powder processing and size reduction. The industry's most progressive mid-sized milling and screening platform offering two pilot-scale processing solutions on a single, common drive.


Flexible and easy to migrate from the lab, this model of the SDx™ Series provides the easiest path from research & development through to full production - sitting between the SLS - Scalable Lab System™ and the SDx™ Series production-scale powder milling & screening platforms.  This is also ideal for Customers who have smaller-scale production runs.

This complements the Fitzpatrick & Quadro range of exchangeable milling and screening platforms.

Easily navigate between the Quadro® Comil® and Quadro® FlexSift security screener as the SMARTdetect technology will recognize the head and automatically make RPM modifications, affording the ability to change heads in seconds.

Exceptional value for your investment - two individual functionalities on a single platform, providing the lowest long-standing cost when compared to the purchase of individual units.
