Lithium Carbonate Rotary Kiln

Lithium carbonate is an inorganic compound, occurring as colorless monoclinic crystals or white powder with the chemical formula Li₂CO₃. It is soluble in dilute acid and slightly soluble in water, with a higher solubility in cold water than in hot water. It is insoluble in alcohol and acetone. It is widely used in ceramics, pharmaceuticals, catalysts, and as a raw material for lithium-ion batteries. Our lithium carbonate pyrometallurgical roasting kilns, acidification kilns, and cooling kilns can be customized to meet customer needs. They are suitable for the pyrometallurgical calcination of raw materials such as lepidolite and spodumene. Models range from Ø0.8 to Ø5.2 m in length and are custom-designed with motors from 45 to 250 kW, capable of processing 120 to 3,000 tons of raw materials daily.

  • Applications

    Suitable for pyrometallurgical production processes such as roasting, acidification, and cooling of lepidolite and spodumene raw materials.

    Product Introduction
    The rotary kiln calcining lithium carbonate equipment uses lepidolite as raw material and undergoes a series of processes, including mixing, roasting, cooling, and crushing. Zhengkuang Machinery has been dedicated to the research of lithium carbonate rotary kilns for many years. We have studied various common problems with these kilns and effectively addressed issues such as ring formation, low production output, and high energy consumption.

    Highlights
    ● The cylinder design fully considers the rotation angle of the cylinder's deflection support, extending the life of refractory bricks and castings.
    ● Large-diameter, low-aspect-ratio idler bearings are used for enhanced reliability, and the bearings are self-aligning.
    ● A new type of open gear cover seal provides excellent sealing performance.
    ● A spring-laminated flexible seal helps improve equipment reliability and service life.

    Operating Principle
    Lepidolite, spodumene, and other raw materials, mixed with other materials, are introduced into the kiln from the upper end of the kiln for roasting. Within the kiln, the materials, affected by the kiln's inclination and rotation, undergo radial and lateral movement. These materials are carried to a higher level, where they exchange heat with the high-temperature flue gas, generating a thermal reaction that achieves the desired roasting effect. The kiln speed is regulated by a variable frequency motor, and the residence time in the kiln can be adjusted according to the reaction time requirements of the reaction materials. The burner is equipped with natural gas flow and air volume monitoring and adjustment functions to meet the adjustment functions of flue gas temperature and flow rate, thereby adapting to the roasting range temperature of the raw materials.

  • Rotary Drum Granulator Rotary Drum Granulator
    The rotary drum granulator is a machine for processing powdered or slurry materials into pellets. Its primary operating method is wet granulation. A sufficient amount of water or steam is used to moisten the base fertilizer within the drum, allowing it to undergo a complete chemical reaction. The drum's rotational motion then creates a squeezing force between the material particles, agglomerating them into pellets. The machine boasts an attractive appearance and is suitable for both cold and hot granulation, as well as the large-scale production of high-, medium-, and low-concentration compound fertilizers.
