Electrostatically supported surface coating of solid particles in
A further advantage of liquid nitrogen is the low surface tension compared to water. Because of the low boiling temperature and the low evaporation enthalpy, liquid nitrogen can be easily evaporated after the mixing or coating process. Finally, a dry and homogenous powder without any change in the state of the solid particles is available.

Cold grinding
Materials such as polymers, elastomers, waxes, paint additives and pharmaceuticals cannot be used efficiently until they are in powder form for further processing. However, the process of comminuting the regrind sometimes proves to be a problem, as many materials have a high temperature sensitivity and tend to melt.
