The vertical roller mill itself is equipped with a powder concentrator, which can remove fine powder in time, reduce the phenomenon of overgrinding and improve the grinding efficiency. The vertical roller mill is less power consuming. The energy consumption of a vertical roller mill is around 75% of that of a ball mill of the same capacity.

Vertical mills comprise 24 conical rollers which are hydraulically pressed onto a horizontal rotating grinding table. The roller axis is inclined at 15o to the table and, as axes of rollers and table do not intersect in the plane of the table. the relative motion involves both rolling and sliding which enhances comminution.
