Laboratory Mill

Lab Grinding Mills In a laboratory setting, most materials used for sampling are non-homogeneous mixtures. The best method of obtaining a small sample of these mixtures is to take a quantity of the material big enough to be compositionally representative, and then reduce it to a fine powder.

Cryogenic Grinding

Various products e.g. elastomers, polymers as well as some color- and tire granules cannot be ground in the same way as conventional bulk goods due to their physical texture, but require special treatment before, during and after the grinding process. Up until now, the industrys approach was always to cool the material using liquid nitrogen, then to grind it on an impact mill or similar

Production of Fine Polymer Powder under Cryogenic

Apr 04, 2002In 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.
