A mill for when every micron matters

grinding, milling and screening

Sturtevant

Designed with the same configuration as larger production mills, the Qualification Micronizer jet mill (photo) allows laboratories to develop powder formulations with desired fine particle sizes on a small scale before proceeding to trial and production quantities. Built for experimental batches of 5–20 g, the versatile Qualification Micronizer can mill up to 0.5 lb/h of material, but can also handle feedrates as low as a few grams per hour to maximize sample recovery. The fines produced have a narrow particle-size distribution and can be milled to diameters as small as a few microns. Compressed air or bottled gas is used to create a high velocity vortex within the micronizer that causes the particles to collide and disintegrate into tiny spheres. This process generates no heat, the company says. — Sturtevant, inc., Hanover, Mass.
