Fine Grind Milling

High target, precise milling in a single, complete stand-alone system


Fine Milling Equipment


Ultra-Fine Powder Grinding

The F10 fine grind mill is an advanced fine powder grinding machine, producing the highest percentage within the target PSD of any existing fine milling technology.

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.

Equipment for Fine Powder Grinding

This ultra-fine powder grinding mill yields the highest percentage of fine particles within the target of any fine milling technology with up to 40% improvement in results when compared to other milling options. Competitive 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 exceptionally narrow particle size distribution (PSD) curves.

The Quadro® Fine Grind Model F10 is a turnkey, automated, stand-alone process system, making 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.
