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
Cryogenic grinding solutions can help you grind more effectively and efficiently using liquid nitrogen. PolarFit® Cryogenic Size Reduction Solutions A cost effective way to achieve required particle sizes and production rates. 800-654-4567, code 3622 GET A
A small Cryogenic Mill with an integrated liquid nitrogen reservoir and insulated housing that processes samples between 0.1 5 grams. It is specifically designed for cryogenic grinding and pulverization of tough and/or temperature sensitive samples in a sealed vial that remains submerged in liquid nitrogen.
It involves embrittlement of the material with dry ice or liquid nitrogen which substantially improves the breaking behavior. RETSCH offers a wide range of laboratory mills suitable for cryogenic grinding: CryoMill, Mixer Mill MM 400, Ultra Centrifugal Mill ZM 200, Knife Mill GRINDOMIX GM 300.
Cryogenic grinding can achieve a very fine level of grind as most hardy materials tend to become brittle when cooled with liquid nitrogen. To produce crumb rubber, it
PolarFit Cryogenic Grinding Solutions for Efficient Size Reduction Our PolarFit size reduction systems use the cooling power of liquid nitrogen to remove heat produced in the grinding process, allowing you to achieve higher yield of particles in your target range, more uniform particle size distribution, higher production rates, Improved product quality and improved process safety due to the
Cryogenic grinding installations are used for: Polyester. Elastomers. Copolymers. Synthetic rubber. Heat sensitive polymers. Composite materials. Cellulose ether. The materials are cooled in a bath- or screw type cooler, generally with liquid nitrogen.
stainless steel special design auger. The auger not only transports the grinding media, but also mixes with liquid nitrogen for greater cooling efficiencies. The liquid nitrogen, a cryogenic fluid with a boiling temperature of –196 0C absorbs heat from the material
In cold grinding, the materials to be ground are cooled and embrittled with cryogenic liquid nitrogen or carbon dioxide. Beim Kaltmahlen werden die zu mahlenden Materialien mit tiefkaltem, flüssigem Stickstoff oder Kohlendioxid gekühlt und versprödet.
The CryoMill is tailored for cryogenic grinding. The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process. Thus the sample is embrittled and volatile components are preserved.
