Ultrasonic Vibrating Screen Sieve for Fine Powder is an advanced screening equipment, which is often used to process fine powder. By combining traditional mechanical vibration with advanced ultrasonic technology—and upgrading the system with an integrated static eliminator—the equipment easily overcomes inter-particle adhesion and static charges. During the screening process, the adhesion and static electricity between material particles can be easily broken, so that the material appears looser on the screen surface, thereby improving screening efficiency and screening accuracy.
Ultrasonic Vibrating Screen Sieve for Fine Powder also has the characteristics of stable screening, large increase in output, and long screen life. Its powerful screening ability and precise screening accuracy can meet the stringent requirements of ultrafine powder screening in different industries.
By integrating advanced ultrasonic technology, this equipment delivers substantial performance breakthroughs for your production line:
High-Frequency Precision: Generates a 36 kHz ultrasonic micro-wave directly on the mesh, preventing fine particles from lodging in the apertures.
Unmatched Fineness: Easily handles difficult materials down to 20 microns (625 mesh) with up to 95%-99% screening accuracy.
Capacity Leap: Boosts processing throughput by 2 to 5 times compared to standard rotary vibrating screens, depending on material characteristics.
Static Elimination: Built-in anti-static grounding devices neutralize friction-induced static charges instantly, keeping powders completely free-flowing.
Take ceramic powder as an example. The powder has the characteristics of high activity, small particle size, and thermodynamic instability. If the product that meets the particle size requirements is not separated in time and the product that does not meet the standard continues to be crushed, it will cause energy waste and excessive refinement of some powders. Furthermore, as particles reach ultra-fine scales, crushing and agglomeration often occur simultaneously. there will be a phenomenon of coexistence of crushing and agglomeration. The agglomeration of particles may even cause the deterioration of the crushing process, making ultrasonic assistance essential to maintain high-throughput material separation.
The integrated ultrasonic system instantly disintegrates these active clusters via continuous high-frequency waves without damaging the ceramic particles. This ensures that qualified powders pass through the mesh immediately, maintaining a narrow and precise Particle Size Distribution (PSD) while maximizing energy efficiency.
Let's look at rubber powder. The 40-80 mesh rubber powder features a light specific gravity, fine particle size, and high elasticity. These characteristics frequently lead to mesh blinding during conventional screening, which not only degrades screening efficiency but also risks powder cross-contamination, ultimately compromising final product quality. Integrating an ultrasonic vibrator into the process effectively eliminates mesh clogging and cross-contamination.
By neutralizing the elastic friction and static build-up between rubber particles and the wire cloth, the ultrasonic wave allows the lightweight rubber powder to slide through seamlessly. This significantly minimizes mesh blinding and cross-contamination, strictly safeguarding the purity and quality grade of the final product.
These systems are widely trusted in powder metallurgy, chemical industry, food, medicine and other industries. They are particularly suitable for screening and grading of fine powder materials with high particle size requirements and easy aggregation. For example, Ultrasonic Vibrating Screen Sieve for Fine Powders can be used in processes such as screening of fine powders, grading of particles, and dust removal of powders.
