How much does it cost to build a coal fired lime kiln
As the core equipment of traditional lime production, the construction cost of coal fired lime shaft kiln is closely related to its production capacity. Taking the coal fired lime kiln with a daily output of 100 tons as an example, the total investment is about 2.4 million yuan, and the specific cost structure is as follows:
The main equipment of the kiln is the core, including the kiln body, burner, and refractory materials, accounting for about 40% of the total investment. Auxiliary equipment such as raw material conveying systems, finished product discharge devices, and dust removal equipment account for approximately 20% of the total investment. The cost of land acquisition and factory construction varies depending on the location, usually accounting for 15% -25% of the total investment. Automated control systems can improve production efficiency, but require an additional budget investment of approximately 10%. Environmental protection facilities such as exhaust gas treatment systems are standard equipment in modern projects, accounting for about 10% of the total investment. The remaining portion is used for labor costs, management expenses, and contingency funds.
Taking the third-generation energy-saving and environmentally friendly lime kiln of Jinyong Kiln Company as an example, the cost of producing 100 tons of kiln type per day is about 2.4 million yuan, calculated based on the production capacity ratio. This data is consistent with the industry average, and through optimized design, the new kiln can reduce energy consumption and operating costs, shortening the investment payback period to 5-6 months.
