The vertical roller mill allows a large amount of air to be passed, so the drying capacity is large; the material in the grinding is in a suspended state, which increases the contact area between the material and the airflow, and the heat exchange condition is good, so the drying efficiency is high. (When the ball mill grinds the wet material ...

Vertical roller mills can have lower power than ball mills in most applications for dry grinding. One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when inter-grinding different materials, the softer materials tend to be ground finer.

Vertical roller mills are developed to work as air-swept grinding mills.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm.
