Design principle of low-energy mechanical lime kiln
The design of low-energy mechanical lime kilns aims to achieve efficient and energy-saving lime production by optimizing the structure and process. The core design principles are as follows:
The lime kiln adopts the principle of countercurrent preheating calcination, where the material moves from top to bottom and the combustion air flows in reverse from bottom to top, achieving efficient heat recovery and utilization. Limestone raw materials enter the crushing chamber and are crushed into small particles through high-speed rotating hammering and grinding, increasing the reaction surface area and improving calcination efficiency. The crushed limestone enters the sintering chamber and is calcined at high temperatures. By precisely controlling the calcination temperature and time, it ensures that calcium carbonate is fully decomposed into calcium oxide and carbon dioxide.
The kiln body design adopts advanced insulation materials and structures to reduce heat loss and improve thermal efficiency. At the same time, optimize the air supply system to achieve "low air pressure, small air volume, and large effect" and reduce power consumption. In addition, the kiln is equipped with efficient dust removal equipment to reduce dust emissions and meet environmental protection requirements.
Through these design principles, low-energy mechanical lime kilns have achieved high efficiency, energy conservation, and environmental protection in lime production, providing strong support for the sustainable development of the lime industry.
