Novel Ultra-Cryo Milling and Co-grinding .Deze pagina vertalen

A novel ultra-cryo milling micronization technique for pharmaceutical powders using liquid nitrogen (LN2 milling) was used to grind phenytoin, a poorly water-soluble drug, to improve its dissolution rate. LN2 milling produced particles that were much finer and more uniform in size and shape than particles produced by jet milling.

Milling Machine: Methods of Milling. Milling .

Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are ple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.
