vertical roller press raw mill flow diagram

  • RawmillWikipedia

    Roller mills. These are the standard form in modern installations occasionally called vertical spindle mills. In a typical arrangement the material is fed onto a rotating table onto which steel rollers press down. A high velocity of hot gas flow is maintained close to the dish so that fine particles are swept away as soon as they are produced.
