Lithium Spodumene Rotary Kiln

The rotary kiln for lithium spodumene is primarily used for calcining lithium spodumene products. In the processes of mixing, calcination, cooling, and crushing, we strive to improve the performance and efficiency of the lithium spodumene calcination rotary kiln equipment. And we have effectively solved the problems of calcium carbonate rotary kiln knotted circle, low output and high energy consumption.


    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 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 are able to 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 upgrade 10% production yield and decrease the thermal consumption by 15%.

    Working Principle

    The raw materials of spodumene or spodumene are delivered to the tail of the spodumene roasting rotary kiln through the feeder, and are calcined in the cylinder. The rotary kiln is inclined to allow the raw materials to move from the higher end to the lower end. The raw materials undergo various processes such as decomposition, calcination, and cooling inside the rotary kiln, and once they become clinker, they are discharged from the bottom of the rotary kiln and enter the cooling machine for further cooling. Fuel enters from the kiln head and, through combustion, releases heat energy within the kiln, so that the raw material is calcined 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
    By adopting an automatic control system, our spodumene rotary kiln can monitor and adjust the temperature, and automatically alarm when the temperature exceeds.
    High output
    In the lithium spodumene calcination rotary kiln, the spodumene raw material can be fully converted into the required crystal phase and fully acidified during the calcination process. Compared with the traditional process, our rotary kiln can obtain higher lithium leaching rate and lithium recovery rate, with an increase of approximately 15%.
    Low energy consumption, and effectively reduce costs
    Our rotary kiln utilizes the heat energy from the high-temperature exhaust gas discharged at the kiln tail to heat the materials or processes that require acidification. This enables effective utilization of thermal energy and reduces the energy consumption of the production line by around 20%.
    Environmental friendly
    The cooling equipment adopts closed low-temperature cycle technology, and an annular air seal device, which effectively prevent dust from leaking.
