Cement grinding Vertical roller mills versus ball mills

2020-3-23  The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently ... These differences between cement grinding and grinding of raw materials made it a

The difference between ball mill and vertical mill in ...

The difference between ball mill and vertical mill in cement grinding Over the last three decades the vertical roller mill has become the preferred ball mill for grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system.

Vertical roller mill for raw Application p rocess materials

2016-1-4  These days, the vertical roller mills have been widely adopted. A)Structure (1) The rollers are hydraulically pressed against a disc table and the feed is ground between the rollers and the disc table. (2) The classifier is housed above the rollers. B)Feature (1) The power consumption level for grinding is lower than that of tube (ball) mill.
