Active lime production line

Active lime production lines are industrial systems specifically designed to produce highly reactive lime, widely used in the steel, chemical, environmental protection, and building materials industries. Jiangsu Haijian Co., Ltd. is a professional manufacturer and company specializing in active lime production lines. We provide specialized equipment for cement production, industrial solid waste incineration, and mining and metallurgical applications. Active lime, due to its high reactivity and excellent physical and chemical properties, plays a vital role in processes such as steelmaking, flue gas desulfurization, and wastewater treatment. It not only effectively removes impurities and improves metallurgical efficiency, but is also used in environmental protection to neutralize acidic substances and reduce pollutant emissions.

The operating principle of an active lime production line is primarily based on the limestone calcination process. After crushing and screening, the limestone raw material is fed into a preheater for initial heating and then into a rotary kiln or shaft kiln for high-temperature calcination. At temperatures ranging from 900°C to 1200°C, the calcium carbonate (CaCO₃) in the limestone decomposes into calcium oxide (CaO) and carbon dioxide (CO₂), producing active lime. After calcining, the lime is cooled and screened, ultimately becoming a highly active product that meets industrial standards. The entire production process requires precise control of temperature, air volume, and calcination time to ensure the activity and quality of the lime. Modern production lines typically utilize automated control systems to achieve efficient, energy-saving, and environmentally friendly production.

The stable operation of an active lime production line depends on effective equipment management and regular maintenance. Because the production line operates in a high-temperature, dusty environment for extended periods, key equipment such as the rotary kiln, preheater, and cooler are susceptible to wear and corrosion. Regular inspection of the kiln lining and refractory materials is essential, and damaged components must be replaced promptly. Auxiliary equipment such as the drive system, fans, and dust removal equipment also require regular lubrication and maintenance to minimize failures. Furthermore, exhaust gas and dust generated during the production process must be treated using efficient environmentally friendly equipment to ensure compliance with emission standards. Operator expertise and standardized operation are also crucial. A sound maintenance strategy not only extends equipment life but also improves production efficiency and product quality.
