Low investment lime kiln type: lime vertical kiln
Choosing the appropriate type of lime kiln is crucial for controlling investment costs in lime production. Among them, the lime vertical kiln has become the economic choice for many enterprises due to its low investment.
The structure of a lime vertical kiln is simple, mostly consisting of a vertical cylindrical kiln body, which is generally composed of a preheating zone, a calcination zone, and a cooling zone. This simple structure results in relatively low construction investment, making it an attractive choice for enterprises with limited funds. Compared with large kiln types such as rotary kilns, vertical kilns have a higher kiln body height but a relatively smaller footprint, and require less equipment and materials, greatly reducing construction costs.
From an operational perspective, lime vertical kilns are relatively easy to operate and have strong adaptability to raw materials, which can meet the firing requirements of various limestone raw materials. Its energy consumption is relatively low. Due to its structural characteristics, the heat energy generated by fuel combustion can directly act on the material, with a fast heating speed and less fuel consumption per unit product, thereby reducing production costs.
Common lime vertical kilns include mixed material vertical kilns, gas vertical kilns, etc. The mixed material vertical kiln uses coke or anthracite as fuel, mixed with limestone and calcined; Gas vertical kilns use gas fuels such as blast furnace gas, coke oven gas, etc.
However, there are also some shortcomings in lime vertical kilns, such as unstable product quality and low degree of automation. But overall, for companies pursuing the least investment, lime vertical kilns are still a worthwhile choice to consider. Enterprises can choose the type and scale of lime vertical kiln reasonably according to their actual situation to achieve maximum economic benefits.
