A Belgian advanced materials company specialized in high-performance resins for automotive, electronics, and aerospace. It sought to improve phenolic microspheres’ particle size uniformity and stability. To achieve this, the company decided to introduce a high-efficiency and precisely controllable classifier system.
After a detailed analysis of the material characteristics (brittle and prone to fine powder generation) and the target particle size distribution (d50 ≈ 10 μm with high size uniformity), Pó ÉPICO provided a custom-designed air classifier system. The system features an adjustable rotor and frequency control technology, enabling precise particle size cut-off and flexible distribution control. Its low energy consumption and minimal temperature rise effectively prevent thermal degradation or agglomeration of the phenolic microsphere material during classification.
In actual operation, the particle size distribution of the classified product improved significantly, with a pass rate exceeding 98%, meeting the strict requirements for electronic encapsulation applications.
Results:
- Concentrated and uniform particle size distribution
- Classification efficiency increased by 30%
- Stable operation with no thermal damage
