Particle size reduction can present challenges to industrial processors, particularly when working with heat-sensitive and tough-to-mill materials. Air Products, Lehigh Valley, Pa., created a microsite to help processors optimize cryogenic grinding operations.
The cryogenic grinding microsite provides technical information about Air Products PolarFit cryogenic size-reduction equipment, which uses liquid nitrogen to cool feed material prior to and during milling. Short videos explain how exposing material to liquid nitrogen can help prevent melting or decomposition, or achieve embrittlement. Effective cryogenic grinding processing can result in a higher yield of particles in the desired target range, more uniform particle size distribution, higher production rates, improved product quality and enhanced process safety due to the nitrogen inertness.
The microsite also includes illustrations that show the size-reduction system configurations offered. To learn more, visit www.airproducts.com/grind3
