of 80mm. The raw materials are mixed in a certain proportion and fed into a vertical roller mill (LOESCHE mill). The vertical roller mill grinds the marital to D 85 of 90µm. The ground product is calcined in a preheater to 850-900℃. After calcination, the materials enter to a rotary kiln and heated to 1450℃ to become clinker.

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.
