Application of Ultrasonic Vibrating Screen in New Energy Materials

Combining mechanical vibration and high-frequency ultrasonic technology, the ultrasonic vibrating screen serves as core equipment for precise classification of ultra-fine powder in new energy materials. It effectively solves common problems including particle agglomeration, screen blocking and low precision of lithium battery cathode and anode materials, conductive agents and metal powder, boosting quality and efficiency of the new energy industry.

Most new energy materials are 500-1000 mesh ultra-fine powder, such as high-nickel ternary lithium, lithium iron phosphate cathode, silicon-carbon anode and graphene conductive agent. These materials feature strong static electricity, easy agglomeration and screen adhesion. Conventional vibrating screens only achieve 80%-85% screening accuracy and require shutdown cleaning every 2 to 3 hours, leading to low efficiency and impurity contamination. Equipped with 28-40KHz high-frequency micro vibration, the ultrasonic vibrating screen disperses aggregated particles and neutralizes static electricity instantly to realize self-cleaning of screens. Its screening accuracy reaches 99.2%, screen blocking rate drops by 90%, and continuous operation time extends to over 8 hours.

In lithium battery cathode material processing, the equipment controls particle size of lithium iron phosphate and high-nickel ternary materials, keeping D50 deviation within ±0.3μm and intercepting over 99% magnetic foreign matters to ensure battery consistency and safety. For highly static silicon-carbon anode materials, dual ultrasonic systems match coarse and fine screening layers respectively. Equipped with Teflon coating and static elimination devices, it raises screening efficiency 5 to 10 times and prevents metal contamination.

For conductive additives and 3D printing metal powder, it disperses carbon nanotubes and conductive carbon black, removes large aggregated particles and improves conductivity. Titanium alloy powder can be classified with high precision under nitrogen protection, with particle size distribution width less than 15μm, complying with additive manufacturing standards.

Made of 304/316L stainless steel with sealed dustproof structure, the equipment meets high-purity and pollution-free requirements of new energy materials. Customized explosion-proof and anti-corrosion versions are available. Widely applied in lithium battery, photovoltaic and energy storage sectors, it has become essential processing equipment for new energy material production.
