How to carry out superfine grinding of lithium iron phosphate? Sichuan giant to solve your worries

Lithium iron phosphate battery is a new type of lithium ion battery that has attracted widespread attention in recent years. Because lithium iron phosphate (LiFePO4) material has high specific energy, long cycle life, stable structure, good safety performance, and low cost, it has quality as a power battery. Many advantages such as high specific energy, low unit price/life, and high working potential. Crushing is a very important link in the production process of lithium iron phosphate. The products processed by airflow crushing principle have narrow particle size distribution, no over crushing and large particles, low fine powder rate and high qualification rate, which are the first choice of most battery material manufacturers. The special jet mill for lithium iron phosphate introduced by Sichuan Giant Powder Equipment Co., Ltd. has the characteristics of high yield, uniform particle size distribution and good particle size morphology. It can be widely used in micron-level experiments and production of battery powder cathode materials.

Lithium iron phosphate special jet mill is a high-speed air flow to achieve dry material ultrafine grinding equipment, by the feeding area, crushing area, grading area and other components. The material enters the crushing zone through the feeding zone, and the crushed material enters the classification zone with the rising airflow under the action of the negative pressure system. The fine particles that meet the particle size requirements enter the cyclone separator and dust collector with the airflow to collect, and the coarse particles that do not meet the particle size requirements return to the crushing zone to continue crushing.

Lithium iron phosphate special jet mill also has the following performance advantages:

1. Airflow pulverizer, with shaping ability, excellent morphology of finished particles, can obtain spherical (potato-like) particles.

2. The particle size distribution is narrow, and the finished product has high tap density.

3, mechanical ultrafine grinding machine, over crushing low, the yield can reach more than 75%-95%.

4. The inside of the equipment can be lined with wear-resistant materials, the finished product has high purity and low equipment wear.

5. Air classifier adopts frequency conversion adjustment, which can be adjusted arbitrarily between 0.5 um-100um.

6. The equipment is stable in operation, and there is no difference or change in continuous startup for a long time.

7, fully enclosed negative pressure operation, automatic control, low noise, anti dust pollution.

Lithium iron phosphate special airflow crusher structure features are:

1. The material contact cavity is lined with ceramic or coating to prevent iron pollution caused by material crushing and ensure the purity of crushed items.

2. No heating. The material is crushed in the state of gas expansion, and the temperature will not rise.

3. The wear is small, the particles collide with each other, and rarely collide with the wall. It can be applied to crush materials below Mohs hardness level 9.

4, low energy consumption, compared with other types of jet mill energy saving 15% to 25%.

It adopts advanced automatic control, real-time display of running status, and easy operation. According to the actual requirements of customers, it can form a central monitoring system with other series equipment control systems to realize remote monitoring.
