With global emphasis on environmental protection and increasingly stringent flue gas emission standards, industrial flue gas desulfurization (FGD) has become a mandatory requirement for power, metallurgy, chemical, cement and other heavy polluting industries. Among diverse desulfurization technologies, limestone-gypsum wet FGD ranks as the most mature, efficient and widely applied solution, and the quality of limestone desulfurization agent is the decisive factor for overall desulfurization efficiency. As a professional grinding equipment manufacturer, HCM (Hongcheng Machinery) supplies a full lineup of high-performance limestone desulfurization mills, acting as the core driving force for efficient and compliant flue gas treatment across the globe.
Why Limestone Desulfurization Matters for Flue Gas Control
Sulfur dioxide (SO₂) emitted from industrial production is the primary culprit behind acid rain, smog and ecological damage, posing severe threats to ecosystems, buildings and human health. Governments across the globe have rolled out mandatory environmental regulations to cap SO₂ emissions, making efficient FGD systems a must for compliant operation. Limestone (main component CaCO₃) is the optimal desulfurization agent thanks to its wide availability, low cost and moderate reactivity. To unlock its full desulfurization potential, limestone must be ground into fine powder (typically 90%+ passing 325 mesh/44μm) to maximize specific surface area and ensure full contact with flue gas. This precision grinding process relies entirely on professionallimestone desulfurization powder mills.
Booming Market Demand for Limestone Desulfurization Mills
Driven by the global "dual carbon" goal and continuous tightening of ultra-low emission policies, the global flue gas treatment market is expanding rapidly, with an annual growth rate of over 15% in the Chinese market alone. Ultra-low emission renovation projects in thermal power, steel and cement sectors are the major growth drivers. As the core supporting equipment for limestone-gypsum wet FGD technology, the demand for high-quality limestone grinding mills is surging. HCM, with its advanced R&D and customized solutions, has become the preferred partner for global FGD projects.

1.HC Series Raymond Mill (Pendulum Mill)
HCM HC series HC1500 Raymond mill produces 150-mesh flue gas desulfurization powder with a production capacity of 12 t/h
As the upgraded generation of traditional Raymond mills, HCM HC series pendulum mills are the ideal choice for medium-scale limestone desulfurization powder production. Featuring a stable pendulum structure, high grinding efficiency and precise classification, this series perfectly meets the 325 mesh standard for desulfurization agents. It boasts low investment cost, easy operation and convenient maintenance, making it the top pick for small and medium-sized FGD auxiliary projects. The mill ensures uniform particle size distribution, boosting desulfurization efficiency and agent utilization rate.
2.HLM Series Vertical Grinding Mill
The HLM1700 vertical mill project for producing 325-mesh
limestone desulfurization powder achieves a production capacity of 32 tons per hour.
For large-scale industrial FGD projects, HCM HLM series vertical mills are the flagship solution. Adopting advanced bed grinding technology, this series integrates grinding, drying, classification and conveying in one unit, featuring large single-machine capacity, low energy consumption and stable operation. It is highly adaptable to different limestone raw materials, capable of producing large quantities of qualified desulfurization powder continuously, and widely used in large thermal power plants, steel mills and cement plants. The HLM vertical mill reduces operating costs significantly while ensuring consistent product quality.
3. HLMX Series Ultrafine Vertical Mill
For high-end FGD projects requiring ultrafine limestone powder with higher reactivity, HCM HLMX series ultrafine vertical mills deliver exceptional performance. This series can produce limestone powder with fineness ranging from 325 mesh to 2500 mesh, with adjustable particle size and high classification accuracy. The ultrafine powder further enhances the desulfurization reaction rate, helping enterprises achieve ultra-low SO₂ emissions and comply with the strictest environmental standards. It combines energy-saving design and stable output, suitable for high-standard desulfurization agent production lines.
4. HCH Series Ultrafine Grinding Mill
HCM HCH series ultrafine ring roller mills are specialized for fine and ultrafine limestone desulfurization powder processing. With a unique roller pressing and grinding structure, this series achieves high grinding efficiency and low energy loss, producing high-purity, uniform limestone powder with excellent fluidity. It is compact in structure, occupies small space, and is suitable for customized small-scale ultrafine desulfurization agent production. The moisture-proof and dust-proof design ensures the reactivity and storage stability of the final desulfurization product.
