Compared to a ball mill, a vertical roller mill is a very versatile mill suitable for, and easily adaptable to, a wide range of products. However, a ball mill can be subject to an …
between vertical mills and ball mills arises from differences in the frequency and energy intensity of ball collisions. The higher efficiency of the vertical mills is due to the higher frequency of lower energy impacts and, by the same token, lower frequency of higher energy impacts when compared to conventional ball mills (Mazzinghy et al., 2013).

The vertical mill product size distribution was predicted by breakage parameters. • The vertical mill breakage mechanisms are the same that observed in ball mills. • Breakage mechanism by attrition or abrasion is not favored in vertical mills. • The vertical mill efficiency factor equal 1.35 worked well for all samples tested. •
The vertical mill has high grinding efficiency and low energy consumption, and the power consumption is only 40%-50% of the ball mill. 7. Finished product quality. Compared with the ball mill, the product of the vertical mill has a higher degree of homogenization and higher purity.
1. Introduction. Ball mill is one of the most commonly used mills for the crushing and grinding of mineral ore. It is generally used to grind material down to the particle size of 20 to 75 μm and can vary in size from a small batch mill up to a mill with outputs of hundreds of tonnes per hour.
The particle size distribution of slag powders prepared by vertical roller mill and ball mill complies with the Rosin–Rammler–Bennett equation. Both slag powders are categorized as Coulomb solids, which exhibit cohesiveness and high flow resistance.
