Introducing the 100-500 Tpd Vertical Shaft Lime Kiln Production Line
Product Introduction
The vertical shaft lime kiln is a tall, vertical apparatus crafted for the precise burning of lime, featuring an innovative all-steel cylindrical structure. Utilizing advanced principles of heat exchange, it harnesses the dynamic interplay between the natural downward movement of materials under gravity and the upward flow of hot gases, ensuring the production of lime that meets the highest standards of quality and purity.stone. Materials are meticulously fed into the top of the kiln and are extracted from the bottom after undergoing calcination, creating a temperature gradient that distinctly forms three zones within the kiln. it is segmented into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, the gently rising temperature courtesy of the flue gas prepares materials; in the calcination zone, they are subjected to intense calcination driven by the heat from fuel combustion; and in the cooling zone, the hot calcined materials transfer their heat to the incoming cold air, thus cooling themselves and providing preheated air to fuel the calcination. This innovative system ensures a smooth, efficient, and thorough calcination process. Leveraging state-of-the-art technology, it capitalizes on cost-effective energy sources, converting environmentally degrading gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy resources.
Product Advantages
1) Energy Efficiency: after burning and releasing heat for calcination, the leftover hot flue gas serves to preheat the incoming material, optimizing energy usage and effectively reducing output flue gas temperature to a reduced and more efficient range of 170~300ºC.
2) The kiln lining is composed of four resilient layers of refractory materials that deliver exceptional thermal insulation. The kiln shell manages to maintain its temperature approximately 60°C above the external environment, effectively curbing excessive energy usage.
3) Typically, these refractory materials boast an impressive lifespan of 6 to 10 years, thereby ensuring enduring durability and cost-effectiveness over the long term.
4) The kiln's remarkable fuel adaptability is unmatched. With the ability to utilize a variety of mixed fuels such as lump coal and coke, high-calorific gases like natural gas and coke oven gas, as well as alternative fuels including converter gas, blast furnace gas, and low calorific sources such as coal gas and generator gas, its flexibility is unparalleled. Fuel oil options like heavy oil and diesel extend its versatility even further.
5) Thanks to the vertical shaft design, the strategic angle of the single bucket elevator, and its cleverly compacted layout, the utilization of space is maximized.
6) Lower When evaluating investment, our kiln stands out with its streamlined steel structure, which features fewer machined components, thereby significantly lowering processing costs. The design not only simplifies installation but also facilitates the efficient construction of refractory materials, ensuring a seamless and hassle-free operational setup.
