Lime vertical kiln is the lowest construction cost lime kiln technology
Lime vertical kiln, with its significant cost advantage, has become a favored choice for many enterprises and can be regarded as the lowest construction cost lime kiln technology.
Structurally, the lime vertical kiln is arranged vertically, and the feeding is arranged at a large angle using a single bucket elevator. The layout of each functional area is compact. This compact design greatly reduces the footprint and lowers the cost of land acquisition. Compared to other types of lime kilns, such as rotary kilns, which occupy a large area and have high land costs, the advantages of vertical kilns in this regard are very prominent.
In terms of construction investment, the structure of the shaft kiln is relatively simple. The steel structure of the kiln has fewer machined parts and lower processing costs. The installation difficulty is not high, and the difficulty of refractory masonry is also low, which reduces labor costs and construction period. Moreover, the kiln skin of the shaft kiln is constructed vertically with four layers of refractory materials, which has good insulation effect. The temperature of the kiln skin can be controlled at around 60 ℃ higher than the ambient temperature, which not only saves energy significantly, but also reduces the loss of refractory materials and lowers long-term operating costs.
From the perspective of equipment matching, there are relatively few supporting equipment and lower costs for vertical kilns. For example, its ash discharge system adopts an energy-saving spiral cone type ash discharge machine, with multiple air outlets, uniform ash discharge, and a circular air duct, which has no dust pollution and low equipment investment.
In addition, vertical kilns have a wide range of fuel adaptability and can use various fuels such as lump coal, coke, natural gas, blast furnace gas, etc. Enterprises can choose lower cost fuels according to their own resource situation to further reduce production costs.
Lime vertical kiln, with its simple structure, compact layout, low-cost supporting equipment, and wide fuel adaptability, has become the lowest construction cost lime kiln technology, providing a cost-effective choice for lime production enterprises.
