04/04/2002· Abstract 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.

Mill cooling uses liquefied cryogenic nitrogen (LIN) or liquid carbon dioxide (LCO2) to significantly reduce the temperatures of the feed material. Cryogenic grinding with in a paddle screw cooler freezes the high fat or oil content in the regrind and makes it brittle. The spices and foodstuffs remain free-flowing and are much easier to grind.

Another mill which is perfectly suitable for cryogenic grinding is the Ultra Centrifugal Mill ZM 200 which accepts larger sample volumes than the mixer mills. This high-speed rotor mill even pulverizes some types of elastomeres, such as polystyrene, without cooling. However, in most cases embrittlement of the material is required.

Cryogenic grinding, also known as freezer milling, freezer grinding, and cryomilling, is the act of cooling or chilling a material and then reducing it into a small particle size. For example, thermoplastics are difficult to grind to small particle sizes at ambient temperatures because they soften, adhere in lumpy masses and clog screens. When chilled by dry ice, liquid carbon dioxide or liq…

Our grinding centers use liquid nitrogen produced by our OGL partner division and the very latest cryogenic freezing technology to lower the temperature of your materials to -320° F (-196° C). This allows us to grind food or polymers that can't be ground at ambient temperatures, or which degrade in heat generated by conventional milling processes.
