Air Products' PolarFit® cryogenic grinding solutions can help you grind more effectively and efficiently, particularly for heat sensitive or tough-to-mill materials. Whether you have an existing cryogenic or ambient milling system that you need to upgrade, or plan to install a new system, we can help.
Our systems use liquid nitrogen to cool down a feed material prior to and/or during milling to either help prevent its melting or decomposition, or achieve embrittlement. While each product is unique, the major benefits of cryogenic grinding are the same: Higher yield of particles in your target range. More uniform particle size distribution.
Cryo grinding is not an efficient milling technique for materials that are already brittle at ambient temperatures, or ones that will not embrittle when transitioned to cryogenic temperatures. These include thermoset resins, epoxies, brittle inorganic compounds (ceramics, glasses, and minerals), and fibrous materials (carbon and fiberglass).

Grinding at cryogenic temperatures creates ultra-fine particles in a very narrow distribution range. Coupled with our customizable sieving system, OGL can evenly classify materials to maximize the yield, stability, and performance of your product. Our sieving systems can be adjusted for a wide variety of application needs.
PolarFit size reduction systems Air Products experienced engineers can help determine which PolarFit system is best for your operation based on your current system, the material you process, and your goals—whether it's our turnkey cryogenic grinding system or components of the system that we retrofit to your existing equipment.
cryogenic grinding or milling system. cryogenic grinding amp attritors union process, inc. cryogenic grinding is most effective when the product is sprayed with liquid nitrogen as it is being conveyed and introduced into the attritor. an additional benefit of cryogenic milling in an internally agitated ball mill is the ability to fully immerse
Therefore, a cryogenic grinding system was designed and developed to cool the spices before feeding to the grinder and also maintain the cryogenic temperature in the grinding zone. The main components of the cryogenic grinding system are a precooler and grinder. The precooler consists of a screw conveyor assembly, a compressor, a liquid ...
A cryo-grinding system principally consists of (i) cryogenic precooler or precooler, and (ii) cryogenic grinder or cryogenic mill. 1.2. Precooler and cryogenic mill. Precooler is the essential component of the cryo-grinding system that removes the desired amount of heat from a spice prior to its entry into the grinding chamber.
Cryogenic grinding – Freezer/Mill® SPEX Europe 's Freezer/Mill® is a programmable cryogenic mill specifically designed for grinding and pulverizing tough or temperature sensitive samples. This technique makes a difference especially for soft, sticky, tough, lubricating and fibrous samples or for samples whose composition or structure ...
There are many ways to make your cryogenic grinding/milling process more efficient. Whether you are looking for a turnkey cryogenic grinding system or components of the system to retrofit your existing process, we can help you find and implement the …
Schematic view of cryogenic grinding system. A double walled, vacuum insulated dewar (IBP make) having capacity of 55 l was used for storage and transfer of LN 2 ( Fig. 4 ). An LN 2 transfer assembly (IBP make) was fixed over the dewar to regulate the flow rate of the liquid nitrogen passing to distributor attached to the conveyor assembly.
