This invention relates to the field of lepidolite calcination technology, and particularly to a high-temperature calcination process and apparatus for lepidolite based on tail gas purification. The apparatus includes a calcination kiln body, and a feed hopper and a discharge cylinder rotatably connected to both ends of the kiln body. The kiln body is equipped with a conveying and screening mechanism for graded calcination of lepidolite, and a recovery and purification mechanism for multi-stage treatment of calcination tail gas is located on one side of the kiln body. This invention achieves graded conveying and processing of lepidolite through the counter-rotation of the kiln body and the rotating cylinder, controlling the transit time of lepidolite within the kiln body. This avoids the phenomenon of some lepidolite being discharged too slowly or too quickly, leading to local over-calcination or incomplete calcination. The graded screening calcination process for lepidolite allows small lepidolite particles to be retained by the screening mesh, delaying discharge and extending the calcination interval, creating a difference in calcination time between small and large lepidolite particles. This effectively avoids the problems of over-calcination of small particles and incomplete calcination of large particles.

The single-point pressure assembly refines grains and releases thermal stress through mechanical impact, directly intervening in welding deformation and cold cracking hazards. The downward cleaning assembly ensures that every welding is performed on a contaminated surface, fundamentally eliminating welding defects such as porosity and slag inclusions caused by dust and oil.
