Fine Grind Milling

Precise, accurate, flexible

High target milling in a single, complete station.

Benefits of the F10 Fine Grind

The Fine Grind delivers advanced fine powder grinding, producing the highest percentage within target of any fine mill technology.

Fine Powder Grinding Mill Machine

For d50 milling in the 5–45 micron (< 325 U.S. standard mesh) range, the Quadro® Fine Grind F10 delivers unsurpassed particle size consistency and maximum on-spec yield. Used to size-reduce diverse materials and those traditionally considered to be difficult to grind such as APIs, excipients, fine chemicals, nutraceuticals and high-value flavors and fragrances. 

Read our blog to learn more about fine powder grinding.

This ultra-fine powder grinding mill yields the highest percentage of fine particles within target of any fine mill technology with up to 40% improvements compared to other milling options such as pin mills. Competing technologies typically don’t incorporate two-stage size reduction technology like the Fine Grind, so they are simply not equipped to replicate the Quadro® Fine Grind’s supremely narrow particle size distribution (PSD) curves.

Fine Grind F10 is a turnkey, automated, stand-alone process system which makes it the ideal addition to your production line when quick and efficient process integration is paramount. The exclusive all-in-one platform design eliminates the need for ancillary equipment.
