A leading quartz processing company in Bengal, sought an advanced ultra-fine grinding and classification system. They were going to produce high-purity quartz powder for demanding electronics and photovoltaic applications. Their objectives were to obtain a fine product with D97 ≤ 10 µm.
Following comprehensive trials of several systems, the customer selected EPIC Powder’s integrated solution. It’s featuring a ball mill paired with an ITC-3 high-precision air classifier.
The ITC-3 air classifier has horizontal high-speed turbine, secondary air intake, and precision speed control. it delivers an exceptionally sharp cut and narrow particle size distribution. The integrated variable-frequency feeder and fully automated PLC system enable single-operator control of the entire production line.
Commissioned in early 2025, the system has exceeded expectations, operating continuously for over 8,000 hours with nearly zero unplanned downtime. The produced ultra-fine quartz powder (SiO₂ ≥ 99.95%) consistently meets the stringent specifications of top-tier photovoltaic crucible and electronic-grade filler manufacturers, significantly enhancing the customer’s market competitiveness.
This project further validates that EPIC Powder‘s ITC series air classifiers offer precision on par with European standards at a more competitive cost, solidifying their position as the preferred choice for high-end ultra-fine processing of quartz, feldspar, and other non-metallic minerals.
