leading to lower efficiency and increased emissions of unburned carbon and other pollutants. Lignite grinding machines are designed to produce lignite powder with the appropriate particle size distribution to meet the requirements of PC boilers, ensuring stable and efficient combustion.
CFB boilers, on the other hand, offer more flexibility in handling lignite with different qualities, including those with high moisture content. In CFB boilers, the lignite powder is mixed with a bed of inert particles, such as sand, and fluidized by the upward flow of combustion air.
The combustion process occurs in a fluidized state, which promotes better mixing and heat transfer. Lignite grinding machines are still essential in CFB boiler applications as they produce lignite powder that can be easily and uniformly distributed in the fluidized bed. The right particle size of the lignite powder helps to maintain the proper fluidization characteristics of the bed and ensures efficient combustion.

In addition to improving combustion efficiency, lignite grinding machines also contribute to reducing the environmental impact of lignite - fired power generation. Finer lignite powder leads to more complete combustion, which reduces the emissions of pollutants such as sulfur dioxide (SO₂), nitrogen oxides (NOₓ), and particulate matter. Some lignite grinding machines are also equipped with integrated drying systems that can reduce the moisture content of the lignite during the grinding process.
