A newly introduced cryogenic grinding mill from Air Products and Chemicals Inc. (Allentown, Pa.; www.airproducts.com/ultrafine) can generate consistent yields of particles between 45 and 250 µm, and in some applications can achieve particle sizes of 10 µm. The ultrafine grinding mill also achieves narrower particle size distributions than conventional impact mills. Known as the PolarFit...

Very seldom is a product of desired size manufactured directly in a process. Size reduction, coupled with screening (classification), is commonly used to achieve desired particle size. In many instances, the final application dictates requirement of small particle size to enhance performance. For example, fine particles enhance dispersion of pharmaceutical ingredients, increase surface coverage of paints...
