100-500 Tpd Vertical Shaft Lime Kiln Production Line
Product Introduction
The vertical shaft lime kiln is a towering, vertical marvel designed for the meticulous calcination of lime. Its innovative, all-steel cylindrical structure is crafted for performance and precision. Harnessing the sophisticated principle of heat exchange, it expertly orchestrates the union of descending materials, driven by gravity, with ascending hot gases, to yield lime of unparalleled purity and quality.stone. The materials are meticulously introduced at the apex and are subsequently retrieved from the base post-calcination. This intricate process creates a temperature gradient within the kiln, dividing it into three specialized zones. it is meticulously segmented into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials are gently acclimated by the warming embrace of flue gas. Progressing to the calcination zone, they undergo a transformation through heat generated by the combustion of fuel. Finally, in the cooling zone, the heated calcined materials gracefully transfer heat to incoming cold air, cooling themselves while simultaneously heating air to assist combustion in the calcination zone. This harmonious system ensures each calcination phase is executed with fluidity and precision. By embracing state-of-the-art technology, it maximizes energy efficiency, turning traditionally polluting gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy sources.
Product Advantages
1) Energy Efficiency: after the calcination process, the residual hot flue gas is ingeniously used to preheat incoming materials, enhancing energy conservation and lowering the output flue gas temperature to an optimized range of 170~300ºC, ensuring minimal energy waste.
2) The kiln lining is composed of four robust layers of refractory materials, offering exceptional thermal insulation. This allows the kiln shell to maintain a temperature around 60°C above ambient, effectively reducing excessive energy usage.
3) Typically, the refractory materials boast an impressive lifespan ranging between 6 to 10 years, ensuring long-term reliability and cost-efficiency.
4) The kiln's fuel adaptability is outstanding. Whether employing mixed fuels such as lump coal and coke, high-calorific gases like natural gas and coke oven gas, or alternative fuels like converter gas, blast furnace gas, and low calorific sources like coal gas and generator gas, it delivers unparalleled versatility. Fuel oil options, including heavy oil and diesel, further broaden its adaptability.
5) Due to the vertical shaft design, the strategically optimized angle of the single bucket elevator, coupled with the intelligently compact layout, space utilization is significantly enhanced.
6) Lower investment requirements are achieved through the kiln's streamlined steel structure with minimal machined components, resulting in substantially lower processing costs. This intelligent design simplifies installation, facilitates the construction of refractory materials with ease, and ensures a seamless operational setup.
