Construction cost of a 100 ton daily coal fired lime kiln
As the core equipment for small and medium-sized lime production, the construction cost of a 100 ton daily coal fired lime kiln is affected by multiple factors and needs to be comprehensively evaluated from the dimensions of equipment selection, construction technology, and environmental protection requirements. According to industry data, the overall investment for such projects usually ranges from 2 million to 3 million yuan, with the following specific composition:
The kiln body is the core part of the cost, and the material, diameter, and refractory layer thickness of rotary or vertical kilns using coal burning technology directly affect the cost. Taking mainstream configuration as an example, the construction cost of kiln body accounts for about 40% of the total investment, which is 800000 to 1.2 million yuan. The auxiliary equipment includes crushers, conveyor belts, dust collectors, etc., which need to meet the continuous production needs. This part of the investment accounts for about 20% of the total cost, which is 400000 to 600000 yuan. Environmental protection facilities have been a key factor in the rising costs in recent years, and desulfurization and denitrification systems, bag filters, etc. need to meet emission standards, with an investment ratio of 10% to 15%, about 200000 to 450000 yuan.
The cost of land acquisition, factory construction, and construction varies by region, with significant differences in foundation treatment costs between plain and mountainous areas, accounting for approximately 25% to 30% overall. Labor costs, management expenses, and unforeseeable expenses account for the remaining 10% to 15%. If modular design or standardized construction is adopted, the budget can be optimized by 10% to 20%. In the current market environment, a budget of 3 million yuan can cover the entire process from equipment procurement to environmental acceptance, but it is necessary to strictly control the quality of the supply chain to avoid a surge in maintenance costs due to low-priced equipment.
