In recent years, the Indian architectural decoration industry has seen a surge in demand for high-performance and high-transparency coatings. A leading specialty materials supplier in India aimed to improve the scratch resistance and weatherability of its products. They planned to process recycled glass into ultra-fine functional fillers with a D50: 2.5μm.
Core Challenges
Extremely Fine Deeltjesgrootte: The required D50 :2.5μm demands high precision in the equipment’s classification system.
Purity Requirements: Glass powder for coatings requires high whiteness and transparency. Metal contamination during grinding must be strictly avoided.
Productivity Balance: The system must maintain a stable output of 50-100kg/h while achieving ultra-fine particles.
The Solution for Ultra-fine Glass Powder Production

The customer ultimately selected the Epic Powder Luchtstraalmolen system. This equipment utilizes the energy generated by supersonic airflow for particle-to-particle self-grinding. It perfectly matches the processing requirements for glass powder.
Key Equipment Features:
Fluidized Bed Opposed Jet Technology: Pulverization is achieved through particle collisions. This reduces equipment wear and ensures the purity of the final product.
Integrated High-Precision Classifier: Equipped with a frequency-controlled horizontal classifying wheel. It stabilizes D50 : 2.5μm by precisely adjusting the rotation speed.
Optional Ceramic Lining: Considering the high hardness of glass, key parts can be protected with ceramics. This prevents the formation of metal black spots.
Operational Parameters & Results
Uitrustingsmodel: Episch poeder Air Jet Mill & Classifying System
Eindfijnheid: D50= 2.5μm
Stable Capacity: 80kg/h (fully meeting the 50-100kg/h target)
Particle Size Distribution (PSD): The distribution is extremely narrow with no oversized particles. This enhances the mirror-like effect of the coatings.
Klantfeedback
The Indian client stated: “The Episch poeder ultra-fine glass poeder apparatuur is very stable while maintaining ultra-fine fineness. The glass powder produced performs excellently in our transparent primers. It significantly improves the film hardness while maintaining excellent transparency.”
