Analysis of Investment Return on Lime Calcination Equipment
The investment return analysis of lime calcination equipment needs to be comprehensively evaluated based on equipment cost, production scale, and market environment. Taking the mechanical fossil ash vertical kiln with a daily output of 100 tons as an example, the equipment investment is about 2 million to 2.5 million yuan, covering the kiln body, feeding system, dust removal device and supporting facilities. The installation and debugging costs are approximately 500000 to 800000 yuan, including site leveling, pipeline laying, and employee training. The additional costs of transportation, taxes, and emergency reserves are approximately 300000 to 500000 yuan, and the total comprehensive investment is approximately 2.8 to 3.8 million yuan.
In terms of operating costs, 1.2 to 1.3 tons of limestone are required per ton of lime, with a raw material cost of approximately 120 to 150 yuan; Coal consumption is about 150 to 180 kilograms, and fuel costs are about 180 to 220 yuan; The cost of water, electricity, and labor is about 50 to 70 yuan, and the total cost is about 400 to 450 yuan. The current market price is about 500 to 550 yuan/ton, with a single ton profit of about 100 yuan. If operated for 300 days a year, the annual profit is about 3 million yuan, and the net profit after deducting taxes is about 2.6 million yuan.
The investment payback period is influenced by equipment energy efficiency, fuel prices, and environmental policies. If low-energy design is adopted, heat consumption can be reduced by 10% to 15%, and the payback period can be shortened to 1.2 to 1.5 years. However, it should be noted that fluctuations in coal prices and increased investment in environmental protection (such as desulfurization and denitrification equipment) may compress profit margins.
Investors need to pay attention to local limestone resource reserves, transportation costs, and downstream industries such as steel and chemical, and dynamically adjust production strategies. For example, by reducing raw material costs through large-scale procurement, or adopting waste heat recovery technology to improve energy efficiency, further optimizing the return on investment.
