Lithium Spodumene Rotary Kiln

The spodumene rotary kiln is mainly used for calcining spodumene products. We aim to enhance the equipment’s efficiency and performance during mixing, calcination, cooling, and crushing. We have effectively resolved the issues of knotted circles, low output, and high energy consumption in calcium carbonate rotary kilns.


    Model: Ø2.2×38m - Ø4.3×62m

    Production Capacity: 120-800TPD

    Applicable Materials: Limestone, clay, iron ore slag, etc.

    Application Fields: Suitable for lithium mica, lithium spodumene raw material etc.

    The rotary kiln for lithium spodumene is composed of a cylinder, support roller, heating transition part, drive gear, sealing device, motor, exhaust chamber, sintering part, and kiln hood. It’s easy and more efficient for you to operate our lithium spodumene rotary kilns.

    When burning lithium spodumene, you can notice the flame status and simulate and display the calcination process by using our industrial TV, it can realize the infrared scanner to directly transmit the situation of the calcined belt to the computer. The utilization of these new technologies makes it easier and more reliable to operate our rotary kilns. Additionally, compared with other equipment of similar specifications, our rotary kilns for lithium spodumene can be upgraded by 10% production yield and decrease the thermal consumption by 15%.

    Working Principle

    The spodumene's raw materials are fed through the feeder and delivered to the tail of the spodumene roasting rotary kiln. Inside the cylinder, the raw materials are calcined. The rotary kiln is inclined, allowing the raw materials to move from the higher to the lower end. Various processes such as decomposition, calcination, and cooling occur inside the rotary kiln until the raw materials become clinker. The clinker is discharged from the bottom of the rotary kiln and enters the cooling machine for further cooling. Fuel enters from the kiln head, and using combustion, releases heat energy inside the kiln, resulting in the calcination of the raw material into clinker. The hot air formed during the heat exchange with the material enters the kiln tail system from the kiln feed end and then is discharged into the atmosphere through the chimney.

    Automatic temperature control
    Our spodumene rotary kiln is equipped with an automatic control system that monitors and adjusts the temperature. It also has an alarm feature that activates when the temperature exceeds the set limit.
    Environmental friendly
    The cooling equipment utilizes closed low-temperature cycle technology and an annular air seal device to effectively prevent dust leakage.
    Low energy consumption leads to effectively reduced costs
    Our rotary kiln uses the heat energy from the exhaust gas, which is discharged at a high temperature from the kiln tail, to heat materials or processes that require acidification. This ensures efficient use of thermal energy and reduces the energy consumption of the production line by approximately 20%.
    High output
    During the calcination process in the lithium spodumene calcination rotary kiln, the spodumene raw material undergoes a complete conversion into the required crystal phase and is fully acidified. This process is more efficient than the traditional one, resulting in a higher lithium leaching rate and an increase in lithium recovery rate of approximately 15%.
