Top 5 Limestone Grinding Mills for Effective Power Plant Desulfurization

Top 5 Limestone Grinding Mills for Effective Power Plant Desulfurization

Introduction

Flue gas desulfurization (FGD) systems in power plants require high-quality limestone powder with precise particle size distribution. Selecting the right grinding mill is critical for achieving optimal desulfurization efficiency while minimizing operational costs. This article evaluates the top 5 limestone grinding technologies, with special focus on solutions from our product portfolio.

1. Vertical Roller Mills (VRM)

Technology Overview

VRMs dominate large-scale FGD applications due to their energy efficiency and ability to handle high throughput. Our LM Series Vertical Roller Mill exemplifies this technology with:

Why Choose Our LM Series?

• 50% footprint reduction vs traditional ball mills
• 30-40% lower energy consumption than ball mill systems
• Negative pressure operation ensures dust emissions <20mg/m³

2. Ultrafine Grinding Mills

For advanced semi-dry FGD processes requiring sub-10μm particles, our SCM Ultrafine Mill delivers unmatched performance:

Key Advantages

• Produces D97≤5μm powder at 0.5-25t/h capacity
• Vertical turbine classifier eliminates coarse particles
• 30% energy saving vs jet mills

3. Trapezium Grinding Mills

Our MTW Series Trapezium Mill offers the perfect balance for mid-range FGD requirements:

Technical Highlights

• Curved air duct design reduces energy loss
• Integrated gear drive with 98% transmission efficiency
• 30% lower maintenance cost than conventional designs

4. Pendulum Roller Mills

For medium-scale FGD systems, our MRN Pendulum Mill provides:

• 2.7-83 TPH capacity range
• Patented oil lubrication system
• 30-325 mesh adjustable fineness

5. Ball Mill Systems

While being phased out in modern plants, ball mills remain relevant for certain FGD configurations. Our GMQG Series offers:

• 0.65-450 t/h capacity
• 0.074-0.8mm output range
• Dry/wet operation flexibility

Selection Guidelines

Capacity Matching

For 500MW power plants, we typically recommend:

• LM280K Vertical Mill (50-170t/h) for wet FGD systems
• SCM1680 Ultrafine Mill (5-25t/h) for semi-dry processes

Maintenance Considerations

Our mills feature:

• Quick-change roller assemblies (LM Series)
• Wear-resistant alloy grinding components (3-5x longer life)
• Remote monitoring capabilities
