How does a vertical raw mill work? LinkedIn

Published Dec 26, 2022. + Follow. A vertical raw mill works by grinding raw material such as cement, clay, limestone, phosphate, and sand into a fine powder. This powder is then passed through themill, where it again becomes part of the normal material circuit. The upgrade is an energy and space-effi-cient solution and in many cases providing a fast return on investment. Fast, easy installation A vertical roller mill capacity upgrade can be achieved without significant changes to existing machinery, so there’s very littleVertical roller raw mill capacity upgrade FLSmidth
