There is no doubt that vertical roller mills offer significant advantages over ball mills regarding their energy efficiency. The specific energy consumption of a ball mill is greater than a vertical roller mill (VRM) that performs the same operations by a factor of between and 2, depending on the ball mill's degree of optimization.

This article, based on the abrasion condition of the rollers on the working field, analyzes the movement characteristics of the material layer of the vertical roller mills from several aspects, such as the tangent speed difference between the roller and the grinding table, the "piles up" phenomenon as well as the flow forms of the material layer. Then we further studied the influence of the ...

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.

Basics of Vertical Roller Mills At its core, a vertical roller mill operates by rotating a cylindershaped mill table while maintaining a set distance between the table and the rollers. The distance between the table and the rollers is known as the 'gap', which is controlled by adjusting the height of the rollers.
