    The immediate advantages of such mills can be easily summed up in the following key points: – 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 indicative maximum of 180 –200 t/h, vertical mills reach up to 300 t/h
