When sieving lithium battery positive and negative materials, people often use ultrasonic vibrating screen for the following reasons:
1. The material is very light;
2. The material is very fine;
3. The material is easy to generate static electricity and easy to agglomerate.
However, if the material is too fine, such as 325 mesh, 400 mesh, 500 mesh etc., the screening efficiency of ultrasonic separator will be very low, the production capacity is small, and the accuracy is not high, which will affect the quality & capacity of the finished products. So, for very fine lithium battery materials, such as graphite, NCM ternary cathode material (lithium nickel cobalt manganese oxide), lithium iron phosphate etc., how to effectively sieve it?
AAREAL vortex turbo screen air classifier can solve this problem very well.
The vortex turbo screen air classifier provides continuous dry material screening, achieving a high efficiency micron-sized accurate separation of 25µm~850µm particles. It is suitable for materials which are difficult to screen with traditional equipments such as vibrating screen, ultrasonic vibrating sieve, tumbler screen etc.. For example, particles with static electricity, materials easy to agglomerate and with light specific gravity, viscous materials containing water or oil and so on. It can be used in food, powder metal, chemical, plastic, cosmetics, pigments, tobacco, pharmaceuticals, minerals, electronics, ceramics and other industries.
1. Fully automatic continuous operation. It can be easily added into the grinding and pneumatic conveying production line.
2. It only takes just a few minutes to realize quick screen replacement.
3. High screening accuracy.
4. With the excellent screen anti-blocking performance, it is almost allowed to screen any type of powders regardless of the specific gravity size, and no matter whether it has the powder properties such as adhesiveness, cohesion, fluidity, hygroscopicity and so on, more suitable for screening lightweight and electrostatic materials. It can easily complete the spherical particle sieving that the ultrasonic screening machine can not manage.
5. Fully enclosed structure, no dust, slight vibration, low noise, no pollution.
