feed stream in hammer mills for grinding tough materials. However, liquid nitrogen is seldom used in jet milling operations due to the swift heat exchange between the material and the grinding gas. The grinding gas heats up the supercooled feed stream, and the material loses its brittleness when it absorbs this heat. Stickiness.

Heat taken away by ventilation systems can accounts for roughly 20% of the total heat discharged by the ball mill. Improving that ventilation system brings more cool air into the inside of the ball bill, gradually reducing the internal temperature. However, the major benefit of using ball mills is the product fineness they can deliver.
