  • 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 (limestone) to calcium oxide (lime) 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. Calcination is carried out in furnaces or reactors (sometimes referred to as kilnsor calciners) of various designs including shaft furna

  • WE’RE ON FIRE FOR THE MOST EFFICIENT LIME KILNS.

    The principle of the PFR kiln, i.e., the calcination of lime in one shaft and the preheating of the stone with the hot kiln gas in the other shaft, is also used in the Finelime ® kiln. Thus its heat consumption is significantly lower compared to rotary kilns. Since 1989, when it was first introduced onto the market,
