Production of Fine Polymer Powder under .

In order to produce fine polymer powders, a special and unconventional cryogenic grinding system was established using liquid nitrogen, where a jet‐vortex mill was used as the grinding mill. The major feature of this grinding process is that heat generation during the grinding period was eliminated. The results suggest that this cryogenic grinding system may be suitable for studying the ...

Cryogenic grinding: an independent voice

polymers to relax. The effect is pronounced: for some grades of polypropylene, cooling from 20°C to –20°C increases stresses by an amount corresponding to a million-fold decrease in contact time during the impact. This is where cryogenic grinding comes in. To allow time for the material's temperature to fall sufficiently, the liquid nitrogen is sprayed onto the feed in a special ...
