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.
(1) vertical roller mill features in high trying ability with hot air direct contact with the material in the mill, maximal feeding moisture of 15% is workable. A separate drying machine and energy for the mill system can be both saved. The vertical roller mill can satisfy the materials in different humidity by adjusting the hot air temperature.
