A traditional jet milling process is often operating with grinding nozzle pressure of around 7 barg at 250˚C. An air compressor must use notable amounts of energy to achieve compressed air at this pressure and temperature. Even more energy is used if the air must be oilfree and dry, which is common in jet milling processes.
