الحصول على السعرThe calcination process normally takes place at temperatures below the melting point of the product materials. One of the most common applications is as a step in the production of Portland cement, in which calcium carbonate (limestone) is calcined at around 850°C to produce calcium oxide (quicklime) and carbon dioxide.
الحصول على السعرCalcination is a heat treatment process in industry to produce lime from pure limestones. This method was applied in a laboratory scale on representative samples from UAE limestones to examine their eligibility for lime production. Limestone rocks occur in several places in the UAE, but largely outcrop in AlAin and Ras Alkaimah zone.
