 · Pulverization may be classified into various classifiions, including: rough, medium, small crushing, coarse, fine, and ultrafine grinding. Thinky Pulverizer Thinky Corporation has designed and manufactured a rotation and revolution nanopulverizer "Nano Pulverizer NP100" for the purpose of nanosize pulverization.

The measured number concentration of ultrafine particles (UFP; ~30 nm diameter) reached 107 particles cm–3 during each machining process. The condensation of thermally evaporated oil vapor was considered to be a major route of ultrafine particle generation during lathe machining and grinding, which used an oilinwater emulsion and

 · Ultrafine grinding of Jew's ear leads to an increase in the FRAP values from – mmol FE/100 g to – mmol FE/100 g. It was reported that ultrafine grinding of food material results into structural changes or damage to the food matrix that in turn releases and exposes the embedded and bound phenolics.
