I. Overview of Materials Lithium carbonate is used to make various lithium compounds, metallic lithium and its isotopes. It is also used to prepare catalysts for chemical reactions. The semiconductor, ceramics, television, medicine and atomic energy industries also have applications. Used as an analytical reagent in analytical chemistry. There are also applications in lithium ion batteries. Used as a coagulant in cement admixtures. Second, the working principle of the equipment: Hot air from the inlet pipe at a suitable speed from the bottom of the dryer into the mixing crushing drying room, the material has a strong shear, blowing, rotating effect, so the material was subjected to centrifugal, shear, collision It is micronized by friction and enhances mass transfer and heat transfer. The material is fed into the dryer by the screw feeder. Under the strong action of the high-speed rotary mixer, the material is impacted and dispersed under the action of friction and shear. The bulk material is quickly crushed and fully contacted with hot air, heated and dried. . After dehydration, the dry powder rises with the hot gas. The grading rings retain large particles. The small particles exit the dryer from the center of the ring, and are recovered by the cyclone separator. They are not dried or the bulk material is thrown by the centrifugal force to the waller and fall back to the end. The part was crushed and dried. Due to the gas-solid two-phase rotation flow, the solid phase inertia is greater than the gas phase, the relative velocity between solid and gas phases is relatively large, and the heat transfer properties between the two phases are strengthened, so the machine has high production strength. II. Lithium Carbonate Eco-Flash Dryer Features: As the material is subjected to centrifugal, shear, collision, and friction, it is atomized in a highly dispersed state and the velocity between the solid and gas phases is relatively large, and the mass transfer heat transfer is enhanced, so that the machine can produce high strength. high. The dry gas enters the bottom of the dryer and generates a strong swirling airflow, which produces a strong scouring effect on the material on the wall and eliminates sticking. In the low-temperature zone of the dryer, the heat-sensitive material does not come into direct contact with the hot surface, and a special device is installed to solve the problem of coking discoloration of the heat-sensitive material. Due to the high gas velocity in the drying chamber, the material residence time is short, achieving high efficiency, rapidity, small equipment, and high output. The upper part of the drying chamber is equipped with a ceramic analysis ring and a swirling piece to control the particle size and temperature of the export material so as to meet the requirements for the final water particle size of different materials.
