Introducing the 100-500 Tpd Vertical Shaft Lime Kiln Production Line
Product Introduction
The vertical shaft lime kiln is a towering marvel of engineering, an all-steel cylindrical structure meticulously designed for the optimal calcination of lime. It harnesses the advanced principle of heat exchange, where the harmonious interplay of gravity-driven material flow and ascending hot gases culminates in the production of premium-grade lime.stone. With materials expertly fed from the summit, the journey culminates in their collection at the base post-calcination. The kiln's internal environment is defined by a sophisticated temperature gradient, delineating three essential zones. it is artfully divided into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials are gently warmed by the ascending flue gas; in the calcination zone, they experience thorough calcination fueled by combustion heat; and in the cooling zone, the hot, freshly calcined materials discharge heat into the incoming cold air, thereby cooling themselves and delivering hot air to support combustion in the calcination zone. This highly efficient system ensures each phase of the calcination process is executed with seamless precision. Leveraging state-of-the-art technology, it optimizes the use of cost-effective energy sources, transforming gases that often threaten the environment-such as converter gas, blast furnace gas, and calcium carbide furnace tail gas-into valuable energy assets.
Product Advantages
1) Energy Efficiency: enhanced bythe utilization of residual hot flue gas for preheating incoming material, this maximizes energy efficiency and efficiently reduces the flue gas temperature to an economical range of 170~300ºC.
2) The kiln lining boasts a four-layered composition of refractory materials, providing unsurpassed thermal insulation. The kiln shell operates at a temperature marginally 60°C above ambient, effectively curbing unnecessary energy expenditure.
3) Typically, the refractory materials enjoy a prolonged lifespan of 6 to 10 years, guaranteeing enduring durability and economic efficiency.
4) The kiln's fuel flexibility is extraordinary. Whether it's traditional mixed fuels like lump coal and coke, high-energy gases such as natural gas and coke oven gas, or alternative options like converter gas, blast furnace gas, and low-calorific sources like coal gas and generator gas, the kiln's versatility remains peerless. Additional fuel options include heavy oil and diesel, expanding its adaptability.
5) The vertical shaft design, complemented by the strategic angle of the single bucket elevator and a thoughtfully compact layout, ensures optimal space utilization.
6) Lower In terms of investment, our kiln features a streamlined steel construction with minimal machining requirements, drastically reducing processing costs. The intuitive design simplifies both installation and the construction of refractory materials, promoting an effortless and efficient operational setup.
