The calcination behaviour of limestone particles (6–90 μm) under furnace injection conditions (1073–1673 K) was determined. Scanning electron microscopic analysis of partially calcined particles revealed that calcination occurred over the total (internal and external) surface area with different calcination rates at different locations.
Limestone Calcination Electric Furnace. Calcination also referred to as calcining is a thermal treatment process in presence of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition phase transition or removal of a volatile fraction The calcination process normally takes place at temperatures below the melting point of the product materials

Nov 25, 2012· Megacrystalline calcite (mCC) breaks apart easily during calcination, and is converted to CaO with difficulty due to its thermal decomposing characteristics that necessitate large heat consumption. To overcome this problem, mCC was calcined using either a microwave furnace or an electric furnace for 15 min and 30 min at 950 °C.
