Vertical lime kiln, just like its name, the shape is erect. It is used for calcination limestone. Due to has low energy consumption, less cover area, less investment, wide applicability fuel, and more advantages, the vertical lime kiln is also widely used in metallurgy, construction materials, calcium carbide, Nanometer calcium carbonate, aerated concrete, sugaring, etc.
The heated limestone is pushed across the floor of the preheater by hydraulic rams, ultimately dropping through the feed hopper and into the rotary kiln. The range of temperatures in the preheater varies from to several hundred degrees in the gas outlet chamber to the calcining temperature (around 1800°F).
The apparatus consists of a suspension preheater with a calcining burner, a rotary kiln, a planetary type multicylinder precooler installed into a unitary construction with the rotary kiln and a main cooler and it aims to take away many problems and defects caused by the conventional system having production capacity more than several thousand tons per day.
