Presenting the groundbreaking 100-500 Tpd Vertical Shaft Lime Kiln Production Line, an innovative solution designed to revolutionize lime production efficiency and quality.
Product Introduction
The vertical shaft lime kiln stands as a towering, vertical marvel engineered for the exacting process of lime burning. Its avant-garde all-steel cylindrical framework is a testament to modern engineering. Harnessing the science of heat exchange, this kiln ingeniously merges the natural gravitational descent of materials with the ascending thermal currents, yielding lime of supreme quality.stone. Materials are meticulously fed from the apex and withdrawn at the base following calcination. Within the kiln, distinct thermal zones form a precise temperature gradient. it is divided into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials are gently warmed by the flue gas; in the calcination zone, they are subjected to calcination via heat from fuel combustion; and in the cooling zone, the hot calcined materials dissipate heat to the incoming cool air, cooling themselves while providing preheated air for combustion in the calcination zone. This sophisticated system ensures each stage of the calcination process operates with precision and thoroughness. Embracing the frontiers of technological advancement, it leverages cost-efficient energy sources, including environmentally challenging gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas, converting potential waste into invaluable energy.
Product Advantages
1) Energy Efficiency: after calcination, the residual hot flue gas preheats incoming materials, maximizing energy utilization and reducing output flue gas temperature to an optimized range of 170~300ºC.
2) The kiln lining comprises four robust layers of refractory materials, ensuring exceptional thermal insulation. The kiln shell maintains a temperature approximately 60°C above the ambient level, significantly curtailing excessive energy usage.
3) Typically, the refractory materials boast an extended lifespan, lasting between 6 to 10 years, ensuring long-lasting durability and cost-efficiency.
4) The kiln showcases exceptional fuel adaptability. Whether utilizing mixed fuels like lump coal and coke, high-calorific gases such as natural gas and coke oven gas, or alternative choices like converter gas and blast furnace gas, it demonstrates unmatched versatility. Additionally, fuel oils like heavy oil and diesel broaden its adaptability further.
5) With its vertical shaft design, the strategic angle of the single bucket elevator, coupled with an intelligently optimized layout, space utilization is elevated to new heights.
6) Lower When evaluating investment, our kiln's streamlined steel structure and reduced number of machined components lead to significantly diminished processing costs. The design simplifies installation and eases the construction of refractory materials, ensuring a seamless transition to operational functionality.
