200TPD durable widely used quick lime rotary kiln with ISO CE approved

Introduction

　Production of quick lime (CaO) is a high-temperature process. It involves endothermic chemical reaction to thermally dissociate calcium carbonate into calcium oxide, with carbon dioxide as by-product.

YUHONG Quick Active Lime kiln can work with vertical preheater and vertical cooler to achieve the advantages like high use ratio of raw materials, complete calcination, even quality, good quality lime, high capacity output, environmental and energy saving, simple operation and longer working life. This kiln is very suitable for limestone calcination for industries like metallurgy, chemical, construction materials and etc.

　The thermal dissociation of limestone takes place at a calcination temperature of 1173K using thermal energy of 3010 kJ/kg of limestone produced On a mass basis, one kg of quicklime is produced from burning 1.786 kg of limestone, releasing 0.786 kg of carbon dioxide.

　　Normally, the heat for calcination is supplied by the combustion of carbon-based fuels. These conventional fuels have relatively high energy density and provide high-grade heat, but as a drawback, produce carbon dioxide both from the calcination reaction and from the combustion process. By replacing fossil fuels with concentrated solar energy as the primary energy source to carry out calcination reaction, the carbon dioxide from combustion is completely eliminated, thus reducing the carbon dioxide from cement industries which are the predominant producers of quick lime. The solar process also ensures production of very pure quicklime, which is not contaminated by combustion by-products.
