Quicklime purposes: a lot of lime and limestone used as building material for later active calcium oxide, is an important raw material in many industries. Limestone can be directly processed into stone and fired into quicklime. There quicklime and slaked lime. The main ingredient is quicklime CaO calcium oxide, the general was massive, pure white, pale gray or pale yellow containing impurities. The main factors affecting the quality of the lime burning: calcining kiln choice. Calcining kiln rational structure for the production of "light burning" to create conditions for the activity of lime, calcium oxide production plant, uniform distribution of fire points, and each segment of logistics proper temperature control, the effect is like firing. Other factors. Charge mode of operation, feeding, ash and kiln seal way, automatic control production levels, technical quality of workers and the like.
