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.

The use of grinding aids increase separator efficiency. The lower bypass and lower coarse grade efficiency of the fine particles means less fines are returned to the mill. This reduces the negative influence on the overall fineness balance around the mill, improving overall grinding efficiency.

Due to limitation of the mill's rotational speed, the smallest ball size is usually restricted to about 15 mm. Cement grinding using stirred mills (Pilevneli and Azizli, 1999) indicates that using smaller media (58 mm range) improves grinding energy efficiency up to 50% using stirred mills. For specialized types of cement, which are finer ...
