Large Capacity Lime Vertical Rotary Kiln for Cement Chemical Clinker Nickel Metallurgy
In-Depth Exploration of Product Features and Benefits
The vertical shaft lime kiln stands as a colossal and expertly crafted vertical structure, perfecting the art of lime burning with unparalleled sophistication. This cutting-edge steel cylinder employs advanced heat exchange principles, harmonizing the downward flow of raw materials with the rising hot gases to achieve lime of superior quality.stone. With meticulous precision, materials are introduced from the top and collected from the base after calcination, with the kiln's temperature gradient defining three distinct operational zones. it boasts a strategic subdivision into the preheat zone, the calcination zone, and the cooling zone..
In the preheat zone, materials exploit the warmth of flue gases; within the calcination zone, they undergo calcination driven by the heat from fuel combustion; in the cooling zone, the hot calcined materials transfer heat to the incoming cold air, cooling themselves while providing heated air for fuel combustion in the calcination zone. This thorough system guarantees an uninterrupted calcination process, integrating state-of-the-art technology to optimize the use of cost-efficient energy sources, transforming environmentally degradable gases like converter gas, blast furnace gas, and calcium carbide furnace tail gas into valuable energy.
Key Advantages of Our Product
1) Unparalleled Energy Efficiency: after the calcination process, the residual hot flue gas preheats incoming material, maximizing energy efficiency and significantly reducing output flue gas temperature to a minimal range of 170~300ºC.
2) The kiln's lining consists of four layers of durable refractory materials, offering exceptional thermal insulation. The kiln shell retains a temperature that is approximately 60°C above ambient, thus minimizing excessive energy consumption.
3) Typically, the refractory materials boast a long lifespan of 6 to 10 years, ensuring durability and cost-effectiveness over time.
4) The kiln features exceptional fuel compatibility. It can efficiently process mixed fuels like lump coal and coke, high calorific gases like natural and coke oven gas, as well as alternative fuels such as converter and blast furnace gas, and lower calorific fuels like coal and generator gas with remarkable flexibility. It also adapts well to fuel oils like heavy oil and diesel, enhancing its versatility.
5) The intelligently designed vertical shaft, featuring a single bucket elevator and a compact layout, optimizes space utilization dramatically.
6) Reduced investment requirements: Our kiln features an efficient streamlined steel structure with fewer machined parts, notably decreasing processing costs. The design simplifies installation, ensuring the smooth construction of refractory materials and seamless operational performance.
