Working principle. 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.
