立窑用高硫烟煤生产优质水泥的生产试验

Producing tests of manufacturing high—quality cement using high sulfur bituminous coal in shaft kiln

介绍了在立窑上采用高硫烟煤进行生产试验的情况。使用高硫烟煤外加萤石,形成氟、硫复合矿化作用,加上高KH、高铁配料,掺入混合材,降低水泥中SO_3含量,能提高立窑水泥产质量。

The productive testing situation using bituminous coal containing high sulfur in shaft kiln has been introduced in this paper. Increasing production and improving quality of shaft kiln cement ran be done by using high sulfur bituminous coal adding fluorite to form fluo — sulfur composite mineralization and high KH,high Fe proportion,mixing admixture to reduce SO_3 content in cement.
