Back to Basics Hammer Milling and Jet Milling Fundamentals

However liquid nitrogen is seldom used in jet milling opera tions due to the swift heat exchange between the material and the grinding gas The grinding gas heats up the super cooled feed stream and the material loses its brittleness when it absorbs this heat Stickiness This property is sometimes related to moisture content However stickiness can also increase with higher fineness
