High Pressure Suspension Roller Mill for Quartz Sand Glass Raw Material Processing

Quartz sand, a critical raw material for glass manufacturing, requires precise particle size distribution and high purity. Traditional grinding methods often fail to meet the stringent requirements of modern glass production. High Pressure Suspension Roller Mills (HPSRM) have emerged as the optimal solution, offering unparalleled precision and efficiency in quartz sand processing.

Technical Challenges in Quartz Sand Processing

1. Particle Size Control

Glass production demands quartz sand with 95% particles between 100-500μm. Conventional ball mills create excessive fines (<75μm) that impair glass melting.

2. Iron Contamination

Metal wear from grinding media can introduce Fe₂O₃ contamination exceeding the 0.01% threshold for clear glass.

3. Energy Consumption

Traditional methods consume 35-50kWh/ton, accounting for 60% of raw material preparation costs.

HPSRM Technological Breakthroughs

1. Advanced Grinding Mechanism

The HPSRM system combines:

• 800-1200kN roller pressure for efficient particle fracture
• Variable-frequency classifier (200-800rpm) for precise size cuts
• Multi-stage separation eliminating <75μm overgrinding

2. Wear-Resistant Design

Our proprietary solutions include:

• Al₂O₃-ZrO₂ composite rollers (HRC≥82)
• Modular roller assembly for quick replacement
• Non-contact labyrinth seals preventing lubricant contamination
