Project Background
- Project Date: 2025
- Customer Location: Iran
- Material: Synthetic Mica
- Equipment Model: Epic Powder MQW20 Jet Mill
- Production Line Configuration: MQW20 Main Unit + High-Precision Air Classifier + Closed-Loop Air System + Pulse Bag Dust Collector
Synthetic mica is widely used in high-end cosmetics (pearlescent pigments), electronic insulation materials, and specialty coatings due to its excellent electrical insulation, high temperature resistance, and chemical stability. To meet downstream customers’ demands for ultra-fine, high-purity, and narrow particle size distribution mica powder, the Iranian client urgently required a stable, efficient, and clean ultra-fine jet mill grinding production line.
