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.
and Maintenance of vertical roller mill Zenith vertical roller mill is totally different from the common hammer crusher, cone crusher and roller crusher in structure and working principle.
