In this detailed technical walkthrough, we explore how a lithium ore rotary kiln transforms raw spodumene into highly reactive beta-phase material through precise high-temperature roasting. You'll see the complete thermal processing workflow, from material feeding and counter-current heating to phase transformation and waste heat recovery. We demonstrate how this continuous 5-200 TPH system achieves over 90% lithium leaching rates while maintaining energy efficiency and operational stability for large-scale battery material production.
