A roller mill is most effective processing materials that are 5 or less on the Mohs scale of hardness. There are a few limitations, but the most practical are soft to medium hard materials. They can also be used to prepare feed for systems producing ultra-fine materials, such as a Raymond Vertical mill, ball mill or Jet-Stream Classifier system.
The vertical roller mill (VRM) is a type of grinding machine for raw material processing and cement grinding in the cement manufacturing process.In recent years, the VRM cement mill has been equipped in more and more cement plants around the world because of its features like high energy efficiency, low pollutant generation, small floor area, etc.. The …
The grinding process in ball mills and vertical roller mills differ fundamentally. In a ball mill the comminution takes place by impact and attrition. The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of the individual particles in the bed, although the ...
For future FGD installations under consideration, the high energy cost associated with ball milling, particularly when pursuing fine grinding, has become a crucial factor raising the need for a quest for alternative milling technology to reduce the costs. ...
