What Is The Latest Price Trend Of Ferric Phosphate?| What Can Be Used To Grind Lithium Iron Phosphate Powder?

HCMilling(Guilin Hongcheng), the manufacturer of lithium iron phosphate grinding mill, learned the latest price trend of iron phosphate from the researcher of Zhongyan Puhua. The price of iron phosphate is about 400000 tons. Iron phosphate is an important raw material for lithium iron phosphate battery. As the "heart" of new energy vehicles, lithium battery accounts for 30%~40% of the vehicle cost. In recent years, the rapid development of new energy vehicle industry has driven the demand for lithium iron phosphate batteries. The market share of lithium iron phosphate increased rapidly, which promoted the rapid expansion of lithium iron phosphate cathode material capacity, and also led to the rapid growth of iron phosphate demand. From the perspective of supply and demand balance, the whole market is in short supply, thus driving up the price of iron phosphate. Therefore, under the influence of market supply and demand, raw material prices and other factors, many enterprises have arranged iron phosphate projects to seek new opportunities for development by expanding their business landscape.

New energy process of ferric phosphate

Lithium iron phosphate battery, as a high performance secondary green battery, has olivine structure lithium iron phosphate (LiFePO4), which can reversibly embed and remove lithium, and has the characteristics of high specific capacity, good cycling performance, stable electrochemical performance, low price, etc. It is the first choice of a new generation of green cathode materials, especially as power lithium ion battery materials.

The new energy process of iron phosphate mainly includes:

1. Drying and dewatering of ferric phosphate;

2. Grinding machine mixing process: 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 (one can operate independently during commissioning). The procedure is as follows: (1) Lithium carbonate grinding: weighing 13Kg of lithium carbonate, 12Kg of sugar, 50Kg of pure water, mixing and grinding for 1-2 hours. Pause. (2) Mixed grinding: add 50Kg iron phosphate and 25Kg pure water into the above mixed solution, and mix and grind for 1-3 hours. Stop the machine and transfer the discharge to the disperser. Take samples for particle size measurement. (3) Cleaning: Weigh 100Kg pure water, clean the grinder in 3-5 times, and transfer all the washing liquid to the disperser.

3. Material dispersion process of the disperser;

4. Spray drying process;

5. The pressure of the hydraulic press is adjusted to 150 tons and 175 tons respectively. The spray dried materials are loaded into the mold, and the pressure is maintained for a time to compact into blocks. Put sagger into pusher furnace. At the same time, several groups of bulk samples are put in and compared with the materials pressed into blocks.

6. The sintering of pusher furnace shall be heated first, and nitrogen shall be supplied. When the atmosphere is below 100ppm, the sagger shall be pushed into the pusher furnace, and the heating period shall be 300-550 ℃ for 4-6 hours; Constant temperature section 750 ℃ 8-10 hours; The cooling section shall be conducted for 6-8 hours and discharging.

7. The ultra-fine roller mill is used to input the materials burned by the pusher furnace into the ultra-fine mill, adjust the rotation speed, and then send them to the ultra-fine mill for grinding after rolling grinding. Take samples from each batch to test the particle size.

8. Screening and packaging: screening and packaging the grinding materials. 5Kg and 25Kg.

9. Inspection and warehousing
