Cryogenic grinding/milling with liquid nitrogen | Air Products

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.
