Sealing Issues in Spodumene Acid Roasting and Acidification Kiln

Competition for new energy lithium resources is fierce, but lithium extraction companies from spodumene are hampered by the same problem – the failure of the acidification kiln seal. Cold air leaks in and hot flue gas leaks out, causing gas consumption to soar by 30% and resulting in drastic temperature fluctuations inside the kiln. The lithium conversion rate is difficult to stabilize at even 85%, and the pervasive sulfuric acid vapor in the workshop poses an environmental hazard, becoming a major obstacle to cost reduction and efficiency improvement for enterprises.

The key to breaking the deadlock lies in customized sealing devices. Zhengzhou Mining Machinery's highly efficient sealing mechanism precisely blocks external air from entering, reducing acid corrosion and heat loss, and boasts a long service life, significantly lowering 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 remained stable at over 98%, and a single production line saved over CNY 200,000 yuan in gas costs annually. Including the reduced environmental costs, the investment in the upgrade was recovered in just six months.

Whether a company's acidification kiln is a small-sized φ0.8×10m or a large-capacity model φ4×60m, Zhengzhou Mining Machinery can customize it according to the actual working conditions. From design and installation to regular inspections after commissioning, the entire process is monitored by dedicated personnel, so that companies don't have to worry about it.

With fierce competition in lithium prices, competitors are already saving costs and increasing production capacity by upgrading their sealing systems. Are you still struggling with air and heat leaks? Quickly upgrade the sealing device of Zhengzhou Mining Machinery's acidification kiln, and get big benefits with a small investment, allowing your production line to easily outperform your competitors!
