effects of alternative calcium sulphate-bearing materials

The vertical mill differs from the ball mill that the vertical mill allows the comminution of the material bed to occur by exposing the material bed to a pressure that is high enough to cause the fracturing of particles using rollers. ... These crystals were generated as a result of the prehydration of cement inside silo [39,40]. Hydrolysis of

vertimill vs ball mill - grinding & classification

vertimill vs ball mill - grinding & classification

One comment that I did not see here is the potential for differential grinding, especially in vertical mills, but also in ball mills. That is when inter-grinding different materials, the softer materials tend to be ground finer. In air swept vertical mills, this can leave a higher quantity of the harder to grind material in the mill
