The Performance of Ball Mill Relative to Vertical Mills. Comminution in ball mills and vertical mills differs fundamentally. In a ball mill, size reduction takes place by impact and attrition. In a vertical mill the bed of material is subject to such a high pressure that individual particles within the bed are fractured, even though the ...
The grinding mechanism of a ball mill is a series of impact and attrition events that occur inside a large rotating drum. The grinding media collide with each other and the material being ground in the drum, creating a large amount of heat. ... Both cement ball mills and vertical cement mills can be used to grind slag. However, vertical cement ...

Previous studies (Mazzinghy, 2012, Mazzinghy et al., 2012) have shown that the higher efficiency of the vertical mill produces larger values of the selection function when compared to the ball mill selection function, by a constant parameter S1 E, from Eq. (5), is multiplied by a scaling factor equal to to correct for the higher efficiency of the vertical mill.
Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than, for example, ball mills with feeds as coarse as 6 mm to products finer than 20 microns. This provides up to a 40% higher energy efficiency . With the Vertimill® simple and robust design, limited liner replacement is required.
