Henan Zhengzhou Mining Machinery Co., Ltd.

Lime vertical 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, it was widely used in metallurgy, construction materials, calcium carbide, Nanometer calcium carbonate, aerated concrete, sugaring, etc. The vertical kiln was manufactured by ZK group with modern new technology, which is an environment protection, save energy, higher machanization and automaticity, quite modern lime kiln. Because it adopts the modern technology, make full use the cheap energy, especially pollution of gas for environment harmful( such as conventer gas, blast furnace gas, calcium carbide furnace tail gas) as the energy, turn waste into wealth. Thus will protect the environment, and produce the high quality lime with lowest cost. To use this new technology enterprise, economic benefits have increased significantly.<br />
 <br />
It should be pointed out that the kiln type especially suitable for the production Nanometer calcium carbonate. Investigate its reason that the concentration of CO2 in flue gas jet can reach more than 35%, CO2 recovery cost is low.<br />
 <br />
Our advantages:<br />
 <br />
1.Save energy;There are preheating zone, calcination zone, cooling zone from the top to bottom of kiln inside. The cooling air blow into the cooling zone from the bottom, though the heat transfer, the goods were cold, and the cooling air was heated, then put into the calcination zone with the heat for burning, thus reduce the energy consumption. The flue gas from the fuel after calcination enter into the preheating, make the material heat to pre-dissociation temperature. The flue temperature fall to 170-300℃, then come out from the kiln.<br />
 <br />
2.The shell of kiln use four layer refractory in vertical masonry, good effect of thermal insulation, the temperature of shell will be controlled higher 60℃ than environment, save energy remarkably.<br />
 <br />
3.Long service life of refractory, the material not directly crash the work surface of refractory, but its fraction with work surface by gravity setting. Thus it greatly reduces the wear rate of refractory, the refractory will be used in 6-10 years in normally.<br />
 <br />
4.Less cover area, because the vertical kiln in vertical layout, feeding use the single bucket elevator in high angle layout, each functional area is decorated compact, greatly reduces the cover area.<br />
