For drying precipitated calcium carbonate in finland

Update date: May 31

Carboclave offers a green technology that employs CO2 for the enhanced manufacturing of prefab cement products. Carboclave originally began as an initiative to find a safer, greener alternative to autoclave curing. The company was incorporated in 2016 after demonstrating a tier of successes in developing, validating, and scaling up a more

    In this work, experiments were performed to determine the filterability of calcium carbonate produced with an alternative calcium carbonate production concept. The concept uses steelmaking slag as raw material and has potential to fix CO2 emissions and utilize steelmaking slag, simultaneously. As calcium carbonate is precipitated in a solution containing ammonium chloride, calcium chloride

    Precipitated calcium carbonate (PCC) is an innovative product derived from lime, which has many industrial applications. PCC is made by hydrating high-calcium quicklime and then reacting the resulting slurry, or “milk-of-lime”, with carbon dioxide. The resulting product is extremely white and typically has a uniform narrow particle size distribution, PCC is well established as a […]

    Drying: The drying is a physical process and no chemical changes to the material are made at this stage. The final stage of the process is water solid separation; water is to be removed from calcium carbonate. this process is completed in two stages viz. making cake by use of centrifuge which contains around 30% moisture

    The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ground product either in dry or slurry form. Precipitated calcium carbonate (CAS: 471-34-1) is produced industrially by the decomposition of limestone to calcium oxide followed by subsequent recarbonization or as a by-product of the
