An industrial materials supplier in Saudi Arabia required the grinding of high-purity ultrafine glass powder for high-performance composite materials.
The project faced two major challenges.
First, glass powder is highly abrasive and can easily cause equipment wear and contamination.
Second, the ambient temperature in Saudi Arabia is extremely high.
The customer required the final product to achieve a particle size of D50: 2.5 µm.
In addition, the system needed to operate stably at a throughput of 100–200 kg/h.
Ultrafine Glass Powder Grinding Solution: Epic Powder MQW Series Jet Mill

A customized closed-circuit production line was designed, centered on the MQW Series fluidized-bed jet mill.
- Precision Ultrafine Grinding:
The MQW Series uses supersonic airflow to induce particle-to-particle collisions.
This “material-on-material” grinding principle significantly reduces wear on the internal surfaces of the equipment. - Full Ceramic Protection Design:
To meet the high-purity requirements of glass powder, alumina ceramic linings were applied to the classifier wheel and material inlet and outlet.
This design effectively eliminated the introduction of metal contaminants. - Environmental Adaptation Optimization:
Considering the extremely hot climate in Saudi Arabia, the cooling modules of the compressed air system were optimized.
This ensured stable grinding air temperature and prevented thermal degradation of the material.

Expert Consulting and Engineering Services
