This project is a 400t/d suspension calcined lime production line in East China. The fuel system is equipped with a Zenith Machinery LM series vertical coal mill. Energy efficiency and emission control were fully considered during the design and manufacturing process. By leveraging advanced combustion technology and thermal control systems, the lime suspension kiln achieves more efficient combustion and heat utilization, thereby reducing energy consumption. This not only improves the company's economic efficiency but also promotes green industrial development, resulting in significant economic and social benefits.
