  • Methods and systems for making and using refined lime flour
    Patent number: 11878913
    Abstract: A system and method of removing grit and contaminants from a lime oxide flour where the lime oxide flour begins as a standard lime flour which has a particle-size distribution of greater than 90% minus 100 mesh and less than 80% minus 200 mesh. The standard lime flour is then refined via classification to a refined lime flour which has greater than 80% minus 200 mesh. The refined lime flour may then be used for formation of lime hydrate at end-user on site production where it is typically less reactive to slaking water temperature variations.
