Case Detailed Description
This project is located in the Shanxi Province of China. This processing facility has long been focused on the development and utilization of limestone deposits. The factory's conventional calcination process has exposed a number of problems, such as high energy consumption, substantial smoke and dust emissions during the production process, and low overall calcination efficiency. These problems make it challenging to improve the purity and output of the products and significantly limit the enterprise's ability to grow sustainably in the face of mounting environmental protection pressure and market competition.
After extensive investigation and careful evaluation, the firm has finally chosen to implement the cutting-edge electromagnetic rotary kiln calcination solution offered by AGICO CEMENT in order to fully handle this sequence of obstacles. The main idea behind this plan is to replace the conventional fuel combustion heating method with cutting-edge electromagnetic induction heating technology. The high-frequency alternating magnetic field produced by the electromagnetic heating system causes the limestone ore inside the kiln to immediately create eddy currents and produce heat, resulting in quick and even heat transfer beginning from the material's interior.
In order to ensure that the working temperature within the rotary kiln could consistently reach and be maintained at the ideal limestone decomposition temperature of 1100°C, AGICO developed an electromagnetic heating system with an output power as high as 6000kW. In addition to providing the conditions required for the full breakdown of limestone (which has the chemical formula CaCO₃ → CaO + CO₂), this high-temperature environment also significantly facilitates the efficient breakdown and volatilization of impurities.
The project has successfully finished its trial operation and formally begun production following careful installation and commissioning. The operation data shows that the new system has produced outstanding outcomes. First off, there has been a notable improvement in the conversion rate of limestone due to the calcination efficiency. The final product, calcium oxide (quicklime) and the calcium hydroxide (slaked lime) that is created during digestion, have reached the highest level of purity in the sector. Second, compared to conventional methods, energy usage has decreased by almost 30%, providing businesses with immediate and significant financial advantages. Lastly, it completely prevents the production of pollutants like smoke and sulfur oxides because the entire heating process does not involve fuel burning. Both the ecological environment of the surrounding areas and the working environment on-site have significantly improved, fully coinciding with the national development path of green manufacturing.
