With the increasing demand for flue gas desulfurization (FGD) in power plants and industrial facilities, high-quality limestone grinding mills have become essential equipment. Shanghai-based manufacturers lead the global market with advanced technologies and reliable solutions. This article evaluates the top 5 suppliers and their flagship products, with special focus on grinding mills optimized for desulfurization applications.
| Model | Capacity (ton/h) | Power (kW) | Fineness (mesh) |
|---|---|---|---|
| SCM800 | 0.5-4.5 | 75 | 325-2500 |
| SCM1680 | 5.0-25 | 315 | 325-2500 |
Our SCM Ultrafine Mill stands out with its 30% energy saving compared to conventional mills, achieving D97≤5μm fineness through patented vertical turbine classification. The wear-resistant roller assembly ensures 8,000+ operation hours in limestone grinding applications.
Another recommended solution is our MTW175G model featuring:
| Capacity | 9.5-25ton/h |
| Main Motor | 160kW |
| Fineness Adjustment | 30-325 mesh |
The curved air duct design reduces pressure loss by 15%, while its modular grinding roller assembly allows quick replacement within 4 hours – critical for maintaining continuous desulfurization operations.
For large-scale FGD projects, the LM220K vertical mill handles 36-105 ton/h capacity with integrated drying/grinding functions. Its compact design reduces footprint by 40% compared to ball mill systems.
MB5X298 model delivers 48-83TPH capacity with unique oil lubrication system, suitable for medium-scale desulfurization plants requiring 30-325 mesh limestone powder.
LUM1836 model achieves 5-30μm fineness with multi-rotor classification technology, ideal for semi-dry FGD processes demanding ultra-fine limestone powder.
| Application | Recommended Model | Fineness | Capacity Range |
|---|---|---|---|
| Wet FGD | SCM1680 | 250-325 mesh | 5-25ton/h |
| Semi-dry FGD | LUM1836 | D97≤30μm | 2.3-15ton/h |
