Ultrafine vertical mill is to use high-speed air to accelerate the particle production speed and collide with the target to crush the material. Its advantage is that the crushed material does not produce pollution. 

Because the compressed high-speed air velocity decreases after crushing, the volume increase belongs to the heat absorption process, and has cooling effect on the material, so it is particularly suitable for ultra-fine grinding of heat sensitive materials.

However, one of the disadvantages of ultrafine vertical mill is the high energy consumption. Therefore, how to reduce energy consumption and improve production efficiency is one of the difficulties in air flow pulverization.
