Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough.
Aug 08, 2013· ok good morning!! friends damring hieght is directly impacting grinding bed of material. its increases mill load. if margine is there may increases and get advantage of production increase.low hiegth and some times looses of energy and creates high vibrations.so adjust according to load and conditions of rollers liners.

On the selection parameters of grinding solutions, Bera had this to say. ´When there are materials difficult to grind, like slag, we would rather prefer a Horomill, than a vertical roller mill, ball mill or anything else. Anything harder to grind means more energy requirement. So it all depends on the type of material to be ground.
grinding of raw materials. The grinding efficiency of the vertical roller mill combined with an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill system. However, despite these benefits, applications of the vertical roller mill for cement grinding are less prevalent.
