Introduction to Lithium Iron Phosphate Calciner - Production Process of Lithium Iron Phosphate
During normal production, two grinders are put into operation at the same time, and the specific feeding and operation of the two equipment are the same. The program is as follows:
1. Lithium Carbonate Grinding: Weigh 13Kg of lithium carbonate, 12Kg of sucrose, and 50Kg of pure water, and mix and grind for 1-2 hours. Pause. 2. Mixed Grinding: Add 50Kg of iron phosphate and 25Kg of pure water to the above mixture, and mix and grind for 1-3 hours. Stop Machine, discharge and transfer to the disperser. Sampling for particle size measurement
3. Cleaning: Weigh 100Kg of pure water and clean the grinder 3-5 times. Transfer all the washing solution to the dispersing machine. 3. In the material dispersion process of the disperser, about 500Kg of the material mixed by 2.2 two grinders (including the material for cleaning the grinder) is transferred to the disperser together, and then 100Kg of pure water is added, the mixing speed is adjusted, and the mixing is fully dispersed for 1-2 hours, waiting for the pump to be pumped into the spray drying equipment. 4. Spray drying process 5. Hydraulic press material pressing and loading respectively adjust the pressure of hydraulic press to 150 tons and 175 tons, load spray dried materials into the mold, hold the pressure for a time, and compact into blocks. Load the sagger and transfer it into the push plate furnace. At the same time, several sets of bulk samples were placed and compared with the compressed materials. 6. Heat up the sintering process in the push plate furnace first, add nitrogen gas to meet the atmosphere requirement of less than 100ppm. Push the sagger into the push plate furnace and follow the heating range of 300-550 ℃ for 4-6 hours; Constant temperature range 750 ℃ for 8-10 hours; The cooling period lasts for 6-8 hours, and the discharge is carried out by rolling the material fired by the pusher furnace into the ultra-fine mill. The speed is adjusted, and after rolling and grinding, it is fed into the ultra-fine mill for grinding. Sample and test the particle size of each batch. 8. Screening and packaging: Grinding materials are screened and packaged. There are two specifications: 5Kg and 25Kg. 9. Inspection and warehousing; Product inspection, labeling and warehousing. Including: product name, inspector, material batch, and date Note: Introduction to Lithium Iron Phosphate Calciner - Production Process of Lithium Iron Phosphate; This introduction is only for visiting
