Small Scale Production Vertical Lime Shaft Kiln Gas Fired Lime Vertical Kiln
Vertical Shaft Kiln Introduction:
Cement Shaft Kiln is used for calcination in cement plant. We offer 50 TPD to 300 TPD vertical shaft kiln on turnkey basis for Cement Plant. Cement Shaft Kiln is modern day answer for cost effective production and a boon for the developing countries. VSK is the advanced technology available worldwide for small & medium entrepreneur.
Vertical Lime Shaft Kiln Our Advantages:
The vertical lime kiln manufactured by ZK group gains the advantages such as, environmental protection, energy saving, high machanization and automaticity.
1. Modern Technology: It adopts the modern technology, making full use of energy, especially pollution gas ( such as conventer gas, blast furnace gas, calcium carbide furnace tail gas) as the energy, turning waste into wealth.
2. Environmentally Friendly: It protect the environment, and produce the high quality lime with lowest cost. To use this new technology enterprise, economic benefits have increased significantly.
3. Minimum decrepitation of solid products and minumum erosion of refrectory linings due to slight movement of particles relative to each other
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.
5. Energy Saving: 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.
6. Long service life of refractory. The material is 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.

Vertical Lime Shaft Kiln Working Principle:
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. In order to guarantee the quality and capacity of lime, finalize the fully automatic production during the production, the special and main equipment for the kiln as follows:
