  • Grinding and calcining of gypsum with Pfeiffer grinding plants

    The calcining of gypsum at ambient pressure and at a relatively low air humidity takes place much more frequently. The plaster obtained is b-hemihydrate. Its chemical formula is the same as that of a-hemihydrate. As, however, the crystal water escaping from the intermediate lattice struc ture encounters less resistance through the sur-rounding atmosphere, this process is almost

    and water vapours. The gypsum has to be pre-crushed before it enters the gypsum kettle. Then it enters via the inlet slide and it is heated indirectly by hot air, which can be of a temperature up to 750ᵒC. The stirring device ensures a uniform calcining process. The exhaust gases and the water vapours forming in the kettle are removed separately. The process is monitored by continuous temperature measurement. When the gypsum

  • Calcination Wikipedia

    The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.
