The Role of Vertical Mills in Desulfurization
Vertical mills play a crucial role in the desulfurization process of power plants. These specialized machines are designed to efficiently grind and crush limestone into fine powder, which is then mixed with water to form a slurry. This limestone slurry is injected into the flue gas stream, where it reacts with sulfur dioxide (SO2) to produce calcium sulfite (CaSO3). The CaSO3 is further oxidized to calcium sulfate (CaSO4), commonly known as gypsum.
The key advantage of using vertical mills for desulfurization lies in their ability to achieve high grinding efficiency and energy savings. Vertical mills employ a vertical roller system that allows for greater control over particle size distribution, resulting in finer and more uniform grinding. This not only ensures better absorption of sulfur dioxide but also reduces the amount of waste generated during the process.

The Role of Vertical Mills
Furthermore, vertical mills have a compact design and require less floor space compared to traditional ball mills or horizontal mills. They are also equipped with advanced control systems that optimize operation parameters, leading to improved overall performance and lower maintenance costs.
Vertical mills offer significant advantages in terms of efficiency, environmental impact, and cost-effectiveness when it comes to power plant desulfurization projects. Their ability to finely grind limestone particles makes them an integral part of modern power generation systems striving for cleaner air emissions while maintaining optimal operational efficiency
