The resulting material is heated and cooled to create lime. After the heating (or "calcinating") process, the lime can be milled again and then hydrated or "slaked.". Union Process has developed and patented an Attritor specifically for milling and slaking lime. The CLS Attritor, which operates in continuous mode, has been used to slake ...

limestone, sedimentary rock composed mainly of calcium carbonate (CaCO3), usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz. Most limestones have a granular texture. Their …

Limestone (calcium carbonate CaCO 3) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of CaCO 3. Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both …
