Ultrafine Sericite Mica Grinding and Classification Production Line in India

Sericite mica is widely used in coatings, plastics, rubber, building materials, and functional fillers due to its excellent lamellar structure, chemical stability, and outstanding insulating properties. With the rapid growth of the coatings and plastics industries in India, market demand for high-fineness, high-purity, and consistently graded sericite mica powder continues to increase. The customer, located in India, owns mature sericite mica mineral resources and planned to build a high-efficiency ultrafine grinding and classification production line to achieve large-scale production of high-end sericite mica powder.

Customer Requirements and Technical Targets

The customer defined clear production objectives and technical specifications:

• Material: Sericite Mica
• Target Fineness: D97 ≤ 10 μm
• Designed Capacity: 5 t/h
• Product Requirements:
  • Narrow particle size distribution with minimal coarse particles
  • Good preservation of lamellar particle morphology
  • Stable and continuous operation suitable for industrial production
• Operational Requirements: Reasonable energy consumption, easy maintenance, and adaptability to local operating conditions in India

Solution: Epic Powder Ball Mill + High-Efficiency Classification System

Considering the moderate hardness, pronounced lamellar structure, and sensitivity to over-grinding of sericite mica, Epic Powder provided a customized closed-circuit grinding solution combining a ball mill and a high-precision air classifier.

Core Equipment Configuration

• Epic Powder Ultrafine Ball Mill
  • Optimized liner design and grinding media configuration
  • Balanced grinding efficiency and protection of lamellar structure
• High-Efficiency Air Classifier
  • Accurate cut point control to ensure D97 ≤ 10 μm
  • Effective reduction of coarse particle contamination and improved product consistency
• Auxiliary Systems
  • Stable feeding system
  • High-efficiency cyclone and pulse dust collection
  • Automated control system

Project Performance

After commissioning, the ultrafine sericite mica grinding and classification production line achieved or exceeded the designed performance targets:

• Final Fineness: D97 ≤ 10 μm, narrow particle size distribution
• Actual Capacity: Stable operation at 5 t/h
• System Stability: Reliable continuous operation with low failure rate
• Product Quality: Well-preserved lamellar structure suitable for high-end filler applications
