Latest technology of lime production line equipment
The lime production line equipment is undergoing technological innovation, driving the industry towards high efficiency and environmental protection. Currently, suspension calcination and oxygen enriched combustion technology have become mainstream trends. Suspension calcination uses high-temperature airflow to suspend and rapidly decompose limestone particles, which can reduce coal consumption by more than 15% and reduce dust emissions. The oxygen enriched combustion technology increases the oxygen concentration in the combustion supporting gas, thereby increasing the thermal efficiency to 85%, which is significantly more energy-efficient than traditional methods.
The application of intelligent control systems has further improved production efficiency. AI algorithms can optimize parameters such as calcination temperature and air volume in real-time, increasing the product qualification rate from 90% to 98%. The Internet of Things technology enables device interconnection, monitoring the temperature inside the kiln and the wear of refractory materials through sensors, early warning of equipment failures, and reducing downtime. For example, a 5G+AR assisted diagnostic system can reduce equipment downtime by 30% and improve operational efficiency by 50%.
The upgrading of environmental protection technology is equally crucial. The waste gas reuse technology converts carbon dioxide in kiln waste gas into food grade dry ice, increasing its added value by 5 times. At the same time, industrial solid waste such as steel slag and carbide slag can replace some limestone raw materials, with a substitution rate of up to 30%, reducing resource dependence. These technologies not only reduce production costs, but also promote the transformation of the lime industry towards a circular economy.
