Spodumene ore roasting rotary kiln for lithium extraction
1.Product Introduction Calcination Rotary Kiln
The Spodumene Rotary Kiln is a high-temperature calcination system
specifically designed to convert natural spodumene from its -phase
to a more chemically active -phase. This phase transition is
critical for improving the efficiency of subsequent acid leaching
processes. By utilizing precise temperature control (typically
1000–1100°C) and optimized material flow, the kiln ensures a
high-efficiency phase change, serving as a core component in
lithium ore extraction.
2.Application Calcination Rotary Kiln
- New Energy Battery Materials: Providing high-purity lithium salt raw materials for lithium-ion
batteries.
- Metallurgy & Chemicals: Used in the preparation of lithium compounds for electrolytic
aluminum, ceramics, pharmaceuticals, and other industries.
- Resource Recovery: Supporting sustainable development through the comprehensive
recovery of lithium resources.
3.Working Principle Calcination Rotary Kiln
Process Flow:
Raw materials enter the kiln body and achieve uniform heating
through the continuous rotary motion.
After roasting, the resulting $beta$-spodumene undergoes acid leaching, purification, and other steps
to be finalized as battery-grade lithium salts.
4.Advantages Calcination Rotary Kiln
High Conversion Efficiency: Dramatically improves lithium leaching rates and optimizes
downstream processing.
Process Stability: An intelligent temperature control system ensures uniform heat
distribution, minimizing product quality fluctuations.
Strong Integration: Seamlessly links with crushing, flotation, and acid leaching
equipment to form a complete lithium extraction production line.
