Ultrafine particle Wikipedia

Ultrafine particles (UFPs) are particulate matter of nanoscale size (less than 0.1 μm or 100 nm in diameter). Regulations do not exist for this size class of ambient air pollution particles, which are far smaller than the regulated PM 10 and PM 2.5 particle classes and are believed to have several more aggressive health implications than those classes of larger particulates.

Ultrafine Grinding with Laboratory Ball Mills Oct 06

Nanotechnology deals with particles in a range from 1 to 100 nm. These particles possess special properties due to their size, as their surface is greatly enlarged in relation to their volume (so-called ‘size-induced functionalities’). Ultrafine particles are, for example, harder and more break-resistant than larger particles.

Oleic acid as grinding aid and surface antioxidant for

ZrH 2 is brittle and easy to grind into ultrafine particles, which can be further thermally dehydrogenated to produce fine metal zirconium powder. However, surface oxidation of ZrH 2 usually occurs during the grinding process. In this study, oleic acid was employed as a grinding aid and surface antioxidant for ultrafine ZrH 2 preparation by wet ball milling in ethanol solution.

Energy Use of Fine Grinding in Mineral Processing

Dec 18, 2013· Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill’s energy budget.
