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.
Vertical raw mill is a type of industrial equipment used to crush or grind materials into small particles. Vertical raw mills are widely used in the concrete and mining fields, and are also used to process gypsum. These units can process both raw and recycled materials, while helping to reduce waste and preserve supplies of these materials.
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.
Please share your thinking according to your experience. And one more thing if, in a vertical raw mill operating manual, it is described that mill is designed up to feeding size is 75 so what is the ratio of size between raw material itself means that what is the ideal sieve analysis result for raw mill feed.
