Ultrasonic Vibrating Screen for Graphene Powder Screening: South Korea Application Case

Project Summary

Project Background

The customer in this case is a new energy materials manufacturer located in South Korea, specializing in the research, development, and production of high-performance carbon materials and graphene composite materials.

During the production process of graphene powder, the raw materials often generate particles with different sizes and a small amount of agglomerated materials after grinding and processing. This leads to uneven particle size distribution in the final powder product.

Traditional screening equipment often encounters several challenges when processing ultra-fine graphene powder, including:

• Ultra-fine powder blocking the screen mesh
• Reduced screening efficiency
• Poor powder flowability
• Difficulty in maintaining stable particle size control

These issues directly affect the performance and consistency of downstream material applications.

The customer required a high-precision screening solution to perform multi-level separation of graphene powder, improve powder consistency, and meet the particle size requirements of different application fields.

Why Recommend Ultrasonic Vibrating Screen for Graphene Powder?

1. Solve Ultra-Fine Powder Mesh Blocking Problems

Graphene powder has extremely fine particle sizes. During the screening process, conventional screening equipment may easily suffer from screen blockage, which reduces screening efficiency.

The SYC series ultrasonic vibrating screen uses high-frequency ultrasonic vibration technology to keep the screen surface continuously clean during operation.

2. Improve Graphene Powder Screening Accuracy

The customer required:

• 625 mesh fine screening
• 325 mesh particle size classification
• 14 mesh removal of impurities and agglomerated particles

The multi-layer ultrasonic vibrating screen can complete multiple particle size classifications within a single machine.

This improves the efficiency of graphene powder classification and ensures more consistent powder quality.

3. Ensure Stable Material Quality

For graphene manufacturers, particle size uniformity directly affects:

• Electrical conductivity
• Dispersion performance
• Subsequent composite processing performance

The ultrasonic vibrating screen helps customers improve batch-to-batch consistency and maintain stable product quality.
