Sealing Issues in Spodumene Acid Roasting and Acidification Kilns
Competition for new energy lithium resources is fierce, but spodumene lithium extraction companies are hampered by the same problem – the failure of the acidification kiln seal. Cold air leakage and hot flue gas leakage not only cause a 30% surge in gas consumption but also lead to drastic temperature fluctuations within the kiln, making it difficult to stabilize the lithium conversion rate even below 85%. The pervasive sulfuric acid vapor in the workshop also poses environmental hazards, becoming a major obstacle to cost reduction and efficiency improvement for these companies.
The key to breaking the deadlock lies in customized sealing devices. Zhengzhou Mining Machinery's high-efficiency sealing mechanism can precisely block the entry of external air, reducing acid corrosion and heat loss, and has a long service life, significantly reducing replacement frequency and costs.

The tangible benefits are even more enticing for lithium companies: After the upgrade, a lithium company in Sichuan saw its thermal efficiency surge from 70% to 90%, the reaction temperature fluctuation within the 200℃-310℃ range was strictly controlled within ±5℃, the lithium leaching rate stabilized above 98%, and a single production line saved over 200,000 yuan in gas costs annually. Including the reduction in environmental costs, the investment in the upgrade was recovered in just six months.
Whether your company's acidification kiln is a small-scale model (φ0.8×10m) or a large-capacity model (φ4×60m), Zhengzhou Mining Machinery can customize solutions according to your actual working conditions. From design and installation to regular post-production inspections, the entire process is monitored by dedicated personnel, eliminating any worries for your company.

In today's fiercely competitive lithium market, competitors are already saving costs and increasing capacity through sealing upgrades. Are you still struggling with air and heat leaks? Upgrade your acidification kiln sealing device with Zhengzhou Mining Machinery now for significant benefits with a small investment, allowing your production line to easily outperform your competitors!
