The rotary kiln is 60 m long and 3 m in diameter. It rotates at 1 rpm. Coal is ground to a fine powder, mixed with air and blown into the rotary kiln, where it ignites, producing the necessary heat. Theoretically, to convert 1 tonne of limestone into lime, 3.17 GJ of heat energy is required, as the chemical reaction occurring is endothermic.
An alternative source of magnesia is from seawater, whereby the magnesia is extracted as magnesium hydroxide by reaction with calcined dolomite ([GLOSS]dolime[/GLOSS]) or lime. The calcination of caustic magnesia, dead-burnt magnesia and dolomite are all carried out in either [GLOSS]rotary kiln[/GLOSS] s or …
Magnesite rotary kiln is based on magnesite and dolomite as raw materials, and the ore is calcined at high temperature to produce finished products, which are mainly used in the manufacture of refractory materials.
Also, rotary kilns are expensive to repair and service. All these reasons led to a gradual con-version from rotary kilns to vertical shaft kilns. A separate technology for manufacturing sintered periclase powders was implemented in the 1970s. It involved calcination and high-temperature sintering of magnesia raw material in various systems.
