Prehydration vertical or ball mill

The prehydration and carbonation of the clinker minerals; These particular mills present a vast series of advantages compared to traditional, horizontal ball mills. Vertical cement mills are able to reach production values which are significantly higher than the ones achievable with traditional ball mills. As the latter are able to reach an
