Inner Mongolia 200-Mesh Bauxite Grinding Project

The processing of bauxite in Inner Mongolia presents unique challenges due to its high hardness, abrasiveness, and variable moisture content. For a 200-mesh (75μm) grinding requirement, selecting the right milling system is critical for productivity and cost efficiency.

Recommended Solutions

1️⃣ Enhanced Raymond Mill

• Upgraded with tungsten carbide rollers and classifier for extended wear resistance (3x lifespan vs standard models)

• Ideal for mid-capacity production (5-15t/h) with low energy consumption

2️⃣ Vertical Roller Mill (VRM)

• Best for large-scale operations (20t/h+) with 30% lower power consumption

• Built-in drying function handles moist bauxite (up to 8% moisture)

3️⃣ Specialized Ball Mill System

• Equipped with alumina-lined grinding media to prevent iron contamination

• Closed-circuit design ensures precise 200-mesh output

Regional Adaptation Tips

❄️ Extreme Cold Measures:

• Preheat hydraulic oil to -40°C rating

• Insulate pipelines to prevent material freezing

🌪️ Dust & Sand Control:

• Turbo-classifiers with sand-proof bearings

• Secondary baghouse filtration for compliance with Mongolia's GB16297-1996 emission standards

Cost-Saving Strategies

• Energy: Hybrid grinding (roller press pre-crushing + ball mill) cuts kWh/t by 18%

• Maintenance: Predictive monitoring system reduces downtime by 40%

• Labor: Automated PLC controls require only 2 operators per shift
