Method of grinding cement clinker |
摘要 |
Method of grinding cement clinkers comprising at least two kinds of clinker phases with differing grindability, comprising the steps:
- feeding the cement clinker (100) to a first milling stage
- grinding the cement clinker (100) in the first milling stage with a setting of grinding power and grinding time that allows grinding an easier to grind phase to a predetermined maximum particle size while a harder to grind phase maintains a particle size larger than the predetermined maximum particle size
- transferring the output from the first mill (101) to a first separator (102) dividing the output into a first fraction (103) with the predetermined maximum particle size and a second fraction (200) with a larger particle size
- transferring the second fraction (200) with a larger particle size to a second milling stage and
- grinding the second fraction (200) with a larger particle size in the second milling stage to a final maximum particle size equal to or smaller than the predetermined maximum particle size. |
