US-2009197780-A1 chemical patent summary.
While ultrafine grinding can improve recovery and reduce downstream reagent requirements, the effect of extra particle size reduction should be balanced by the cost of additional grinding energy. For example, the Deswik TM Mill reduced a feed with d 90 of 89 µm to …
A problem in the preparation of ultrafine particle is long grinding time so high energy demands and contamination due to wear of grinding bodies. Previous studies showed that grinding process depends not only on the specific energy input (i.e. the overall energy put into the milling chamber related to the weigth of the ground material) but also ...
If, for example, very elastic materials need to be ground or volatile components have to be preserved for further analysis, it is essential to carry out cryogenic grinding. The use of liquid nitrogen helps to embrittle the sample, thus improving its breaking properties, and preventing volatile substances from escaping due to the frictional heat produced by the grinding process.
