High grinding efficiency. Adopting the advanced material layer grinding principle, the power consumption of the system is 20-30% more energy-saving than the ball mill. As the moisture of the raw material increases, the power-saving effect is more significant; 2. Large drying capacity.

Occasionally, the mill is preceded by a hot-air-swept hammer mill which does most of the drying and produces millimetre-sized feed for the mill. Ball mills are rather inefficient, and typically require 10–20 kW·h of electric power to make a tonne of rawmix. The Aerofall mill is sometimes used for pre-grinding large wet feeds.
