Low cost of burning lime in vertical kiln
The vertical kiln has become the preferred scheme for many small and medium-sized enterprises due to its low cost in the production of lime. Its cost advantages are mainly reflected in the following aspects:
First of all, the vertical kiln equipment investment is small, the structure is simple, the floor area is small, the construction period is short, compared with the rotary kiln and other large equipment, the preliminary investment can be reduced by 30% - 50%, especially suitable for small and medium-sized enterprises with limited funds.
Secondly, the energy consumption of vertical kiln operation is low. Its vertical structure is beneficial to heat energy accumulation, with less heat loss during calcination and higher heat efficiency. At the same time, the vertical kiln can use low-heat value fuels, such as coal gangue, coke oven gas, etc., to further reduce the fuel cost.
Moreover, the vertical kiln is easy to operate and maintain, and the labor cost is low. The automatic distribution and ash discharge system reduces the labor investment, and only a small number of technical personnel are required for daily maintenance, reducing the labor and management costs.
In addition, the vertical kiln has strong adaptability to raw materials without strict screening. Low grade limestone can be used to reduce the purchase cost of raw materials.
To sum up, the vertical kiln realizes the low-cost operation of lime production through the cost optimization of equipment, fuel, manpower and raw materials, which provides a significant price advantage for enterprises in the market competition.
