Indirect Electric Heating Rotary Kiln for High Temperature (1050°C) Thermal Treatment with Customizable Capacity
Our electrically heated indirect rotary kilns provide a versatile thermal treatment solution for processes up to 1050°C. These kilns are particularly effective for beta spodumene to lithium sulphate conversion, supporting carbon footprint reduction and carbon capture initiatives where process CO2 emissions are a concern.
Our indirect rotary kilns accommodate diverse raw materials including alumina, bauxite, vanadium salts, and specialized applications like beta spodumene treatment in lithium processing. Available in sizes from 1m to 20m diameter and up to 90m length, we also offer natural gas heating options for lower-temperature applications where electric heating isn't viable.
