At present, with the vigorous development of the new energy industry, lithium iron phosphate as an important lithium ion battery cathode material, its quality and performance play a decisive role in the overall performance of the battery. In the production of lithium iron phosphate, the screening link is very important, which directly affects the particle size distribution and purity of the product. As an advanced screening equipment, ultrasonic rotary vibrating screen is gradually emerging in the field of lithium iron phosphate screening, providing an effective solution for improving product quality and production efficiency.

Properties of lithium iron phosphate

Lithium iron phosphate has olivine structure and its crystal structure is stable, which makes the material have good thermal stability and cycle life. From the point of view of physical properties, lithium iron phosphate powder is usually a small particle size, generally between a few microns to tens of microns, and has a certain viscosity and adsorption. This fine particle size and special physical properties determine the need for special treatment in the screening process.

Working mechanism of ultrasonic system

Ultrasonic transducer is one of the core components of ultrasonic rotary vibrating screen. It converts high-frequency electrical energy into high-frequency mechanical vibration and applies this vibration to the screen through a transmission device. When the material moves on the screen, the high-frequency vibration of the ultrasonic wave can effectively break up the material aggregate, while reducing the friction and adhesion between the particles and the screen. Under the action of ultrasonic wave, the screen surface produces high-frequency micro-vibration, so that the screen hole is always unblocked, and the phenomenon of screen blockage is avoided. This unique working mechanism enables the ultrasonic rotary sieve to efficiently screen fine-grained, viscous materials such as lithium iron phosphate.

The advantage of ultrasonic rotary vibrating screen in the screening of lithium iron phosphate

1. Efficient screening, improve production capacity

2. High precision screening to ensure product quality

3. Reduce screen clogging and extend screen life

4. Reduce the risk of impurity introduction and ensure product purity

With the continuous development of the new energy industry, the requirements for the quality and output of lithium iron phosphate will continue to increase, and the ultrasonic rotary sieve is expected to be more widely used in this field, playing an important role in promoting the development of the new energy industry.
